We're dividing 680045 by 31 
We want to figure out the number of times 680045 can be divided by 31.

Going ahead to step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 31

On to step 2:
When dividing 68 by 31, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 6 after subtracting 62 from 68.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 31

Going ahead to step 3:
31 can be fit into 60 1 times, resulting in a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 31 from 60, we get 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 31

Going ahead to step 4:
When dividing 290 by 31, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 219.0
Deduct 279 from 290 and we're left with 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 31

Step 5:
If we divide 114 by 31, we get 3 and a remainder of 21.
The next digit of our result is 3. 
Result so far: 2193.0
Deduct 93 from 114 and we're left with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 31

Advancing to step 6:
When dividing 215 by 31, we get 6 with a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 21936.0
Subtract 186 from 215 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
If we divide 290 by 31, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 21936.9
Deduct 279 from 290 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
The number 31 fits into 110 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 21936.93
If we subtract 93 from 110, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
170 divided by 31 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 21936.935
Deduct 155 from 170 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
31 can be fit into 150 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 21936.9354
If we take 124 away from 150, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
The number 31 fits into 260 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 21936.93548
Deduct 248 from 260 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
If we divide 120 by 31, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 21936.935483
Deduct 93 from 120 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
If we divide 270 by 31, we get 8 and a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 21936.9354838
Subtract 248 from 270 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
31 can be fit into 220 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 21936.93548387
If we take 217 away from 220, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 21936.93548387, with a leftover of 3e-09.
