We look at the division of 31858457 by 721 
We're looking to find how many times 721 goes into 31858457.

On to step 1:
When dividing 3 by 721, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 721

Advancing to step 2:
721 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 721

Let's proceed to step 3:
721 can be fit into 318 0 times, resulting in a remainder of 318.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 318 after subtracting 0 from 318.
Grab the next digit (5) from the dividend, add it to 318, then carry on: 3185 / 721

Let's proceed to step 4:
If we divide 3185 by 721, we get 4 and a remainder of 301.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 2884 from 3185 and we're left with 301.
Append the next digit (8) from the dividend to 301 and continue with: 3018 / 721

Step 5:
The number 721 fits into 3018 4 times, leaving a remainder of 134.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we subtract 2884 from 3018, we get 134.
Bring next digit (4) of the dividend behind the 134 and repeat the process: 1344 / 721

Moving on to step 6:
721 can be fit into 1344 1 times, resulting in a remainder of 623.
The number 1 becomes the next digit in our result. 
Result so far: 441.0
If we take 721 away from 1344, we end up with 623.
Take the next digit (5) from the dividend and append it to 623, then repeat: 6235 / 721

Step 7:
721 can be fit into 6235 8 times, resulting in a remainder of 467.
Use 8 as the next digit of our solution. 
Result so far: 4418.0
Deduct 5768 from 6235 and we're left with 467.
Append the next digit (7) from the dividend to 467 and continue with: 4677 / 721

On to step 8:
The number 721 fits into 4677 6 times, leaving a remainder of 351.
The number 6 becomes the next digit in our result. 
Result so far: 44186.0
Subtract 4326 from 4677 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 9:
721 can be fit into 3510 4 times, resulting in a remainder of 626.
Write down 4 as next digit of the result. 
Result so far: 44186.4
If we take 2884 away from 3510, we end up with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Going ahead to step 10:
The number 721 fits into 6260 8 times, leaving a remainder of 492.
Record the quotient 8 as the next digit in the result. 
Result so far: 44186.48
The remainder is 492 after subtracting 5768 from 6260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 11:
The number 721 fits into 4920 6 times, leaving a remainder of 594.
The number 6 becomes the next digit in our result. 
Result so far: 44186.486
If we subtract 4326 from 4920, we get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Going ahead to step 12:
5940 divided by 721 is 8 with a remainder of 172.
Put 8 as the next digit of the answer. 
Result so far: 44186.4868
Deduct 5768 from 5940 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 13:
1720 divided by 721 is 2 with a remainder of 278.
The next digit of our result is 2. 
Result so far: 44186.48682
If we subtract 1442 from 1720, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 14:
721 can be fit into 2780 3 times, resulting in a remainder of 617.
The number 3 becomes the next digit in our result. 
Result so far: 44186.486823
The remainder is 617 after subtracting 2163 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Moving on to step 15:
The number 721 fits into 6170 8 times, leaving a remainder of 402.
Write down 8 as next digit of the result. 
Result so far: 44186.4868238
Subtracting 5768 from 6170 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 16:
4020 divided by 721 is 5 with a remainder of 415.
The number 5 becomes the next digit in our result. 
Result so far: 44186.48682385
The remainder is 415 after subtracting 3605 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

After the division, we end up with 44186.48682385 and a remainder of 4.15e-07.
