We look at the division of 637501 by 31 
Let's see how many times 31 fits into 637501.

Advancing to step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 31

On to step 2:
31 can be fit into 63 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 62 from 63 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 31

Step 3:
If we divide 17 by 31, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 31

Advancing to step 4:
When dividing 175 by 31, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 205.0
Subtracting 155 from 175 leaves us with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 31

Advancing to step 5:
If we divide 200 by 31, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 2056.0
If we subtract 186 from 200, we get 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 31

Let's proceed to step 6:
31 can be fit into 141 4 times, resulting in a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 20564.0
If we subtract 124 from 141, 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 7:
31 can be fit into 170 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 20564.5
The remainder is 15 after subtracting 155 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
When dividing 150 by 31, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 20564.54
Subtract 124 from 150 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
The number 31 fits into 260 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 20564.548
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 10:
31 goes into 120 3 times with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 20564.5483
The remainder is 27 after subtracting 93 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 11:
If we divide 270 by 31, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 20564.54838
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.

Advancing to step 12:
If we divide 220 by 31, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 20564.548387
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.

Moving on to step 13:
The number 31 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 20564.548387
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
If we divide 300 by 31, we get 9 and a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 20564.54838709
If we take 279 away from 300, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 20564.54838709 with a remainder of 2.1e-08.
