Let's divide 655121 by 31
Our goal is to divide 655121 by 31.

Step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 31

Step 2:
If we divide 65 by 31, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 62 away from 65, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 31

Advancing to step 3:
35 divided by 31 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 31 from 35 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 31

Let's proceed to step 4:
When dividing 41 by 31, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 211.0
If we subtract 31 from 41, we get 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 31

Going ahead to step 5:
If we divide 102 by 31, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 2113.0
If we subtract 93 from 102, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 31

Moving on to step 6:
91 divided by 31 is 2 with a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 21132.0
Deduct 62 from 91 and we're left with 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:
The number 31 fits into 290 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 21132.9
If we take 279 away from 290, we end up 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.

Let's proceed to step 8:
When dividing 110 by 31, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 21132.93
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.

Step 9:
When dividing 170 by 31, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 21132.935
Subtract 155 from 170 to get 15.
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 10:
31 goes into 150 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 21132.9354
Subtracting 124 from 150 leaves us 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.

Let's proceed to step 11:
If we divide 260 by 31, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 21132.93548
The remainder is 12 after subtracting 248 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
31 goes into 120 3 times with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 21132.935483
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.

Advancing to step 13:
270 divided by 31 is 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 21132.9354838
Subtracting 248 from 270 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
If we divide 220 by 31, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 21132.93548387
If we subtract 217 from 220, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 21132.93548387 and a remainder of 3e-09.
