Let's divide 616431 by 31
Our goal is to divide 616431 by 31.

Moving on to step 1:
When dividing 6 by 31, we get 0 with 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.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 31

On to step 2:
61 divided by 31 is 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 31 away from 61, we end up with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 31

On to step 3:
31 goes into 306 9 times with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 279 from 306 leaves us with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 31

On to step 4:
31 goes into 274 8 times with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 198.0
Subtracting 248 from 274 leaves us with 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 31

Step 5:
The number 31 fits into 263 8 times, leaving a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 1988.0
Deduct 248 from 263 and we're left with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 31

Going ahead to step 6:
If we divide 151 by 31, we get 4 and a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 19884.0
The remainder is 27 after subtracting 124 from 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
If we divide 270 by 31, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 19884.8
The remainder is 22 after subtracting 248 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
The number 31 fits into 220 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 19884.87
The remainder is 3 after subtracting 217 from 220.
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 9:
30 divided by 31 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 19884.87
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
31 goes into 300 9 times with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 19884.8709
The remainder is 21 after subtracting 279 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
210 divided by 31 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 19884.87096
Subtracting 186 from 210 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
The number 31 fits into 240 7 times, leaving a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 19884.870967
Subtracting 217 from 240 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 13:
The number 31 fits into 230 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 19884.8709677
If we take 217 away from 230, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 19884.8709677, with a leftover of 1.3e-07.
