We look at the division of 13255657 by 431 
We're looking to find how many times 431 goes into 13255657.

Let's proceed to step 1:
431 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 431

Advancing to step 2:
When dividing 13 by 431, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 431

Advancing to step 3:
431 goes into 132 0 times with a remainder of 132.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 132 after subtracting 0 from 132.
Fetch the next digit (5) from the dividend, attach it to 132 and continue: 1325 / 431

Let's proceed to step 4:
431 goes into 1325 3 times with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1293 from 1325 and we're left with 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 431

Step 5:
The number 431 fits into 325 0 times, leaving a remainder of 325.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtract 0 from 325 to get 325.
Grab the next digit (6) from the dividend, add it to 325, then carry on: 3256 / 431

Advancing to step 6:
If we divide 3256 by 431, we get 7 and a remainder of 239.
Record the quotient 7 as the next digit in the result. 
Result so far: 307.0
If we take 3017 away from 3256, we end up with 239.
Grab the next digit (5) from the dividend, add it to 239, then carry on: 2395 / 431

On to step 7:
431 can be fit into 2395 5 times, resulting in a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 3075.0
If we take 2155 away from 2395, we end up with 240.
Include the next digit (7) from the dividend after 240, then repeat: 2407 / 431

Moving on to step 8:
When dividing 2407 by 431, we get 5 with a remainder of 252.
Record the quotient 5 as the next digit in the result. 
Result so far: 30755.0
Deduct 2155 from 2407 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 9:
431 goes into 2520 5 times with a remainder of 365.
Write down 5 as next digit of the result. 
Result so far: 30755.5
Deduct 2155 from 2520 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 10:
431 goes into 3650 8 times with a remainder of 202.
The number 8 becomes the next digit in our result. 
Result so far: 30755.58
The remainder is 202 after subtracting 3448 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 11:
431 goes into 2020 4 times with a remainder of 296.
Record the quotient 4 as the next digit in the result. 
Result so far: 30755.584
The remainder is 296 after subtracting 1724 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 12:
If we divide 2960 by 431, we get 6 and a remainder of 374.
The next digit of our result is 6. 
Result so far: 30755.5846
Subtract 2586 from 2960 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 13:
When dividing 3740 by 431, we get 8 with a remainder of 292.
Record the quotient 8 as the next digit in the result. 
Result so far: 30755.58468
Subtract 3448 from 3740 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 14:
When dividing 2920 by 431, we get 6 with a remainder of 334.
Write down 6 as next digit of the result. 
Result so far: 30755.584686
The remainder is 334 after subtracting 2586 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 15:
431 goes into 3340 7 times with a remainder of 323.
Write down 7 as next digit of the result. 
Result so far: 30755.5846867
Deduct 3017 from 3340 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Let's proceed to step 16:
431 can be fit into 3230 7 times, resulting in a remainder of 213.
The next digit of our result is 7. 
Result so far: 30755.58468677
If we take 3017 away from 3230, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

The final outcome is 30755.58468677, with a leftover of 2.13e-07.
