We're dividing 20258936 by 431 
We want to figure out the number of times 20258936 can be divided by 431.

Going ahead to step 1:
431 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 431

Let's proceed to step 2:
If we divide 20 by 431, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 431

Step 3:
The number 431 fits into 202 0 times, leaving a remainder of 202.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 202, we get 202.
Grab the next digit (5) from the dividend, add it to 202, then carry on: 2025 / 431

Going ahead to step 4:
If we divide 2025 by 431, we get 4 and a remainder of 301.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 1724 from 2025 to get 301.
Take the next digit (8) from the dividend and append it to 301, then repeat: 3018 / 431

Advancing to step 5:
431 can be fit into 3018 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we take 3017 away from 3018, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 431

Moving on to step 6:
If we divide 19 by 431, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 470.0
Subtract 0 from 19 to get 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 431

Step 7:
431 can be fit into 193 0 times, resulting in a remainder of 193.
Record the quotient 0 as the next digit in the result. 
Result so far: 4700.0
The remainder is 193 after subtracting 0 from 193.
Bring next digit (6) of the dividend behind the 193 and repeat the process: 1936 / 431

On to step 8:
When dividing 1936 by 431, we get 4 with a remainder of 212.
Record the quotient 4 as the next digit in the result. 
Result so far: 47004.0
If we subtract 1724 from 1936, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 9:
2120 divided by 431 is 4 with a remainder of 396.
Put 4 as the next digit of the answer. 
Result so far: 47004.4
Deduct 1724 from 2120 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 10:
If we divide 3960 by 431, we get 9 and a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 47004.49
The remainder is 81 after subtracting 3879 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 11:
If we divide 810 by 431, we get 1 and a remainder of 379.
Use 1 as the next digit of our solution. 
Result so far: 47004.491
If we take 431 away from 810, we end up with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Step 12:
The number 431 fits into 3790 8 times, leaving a remainder of 342.
The number 8 becomes the next digit in our result. 
Result so far: 47004.4918
If we take 3448 away from 3790, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 13:
431 can be fit into 3420 7 times, resulting in a remainder of 403.
Record the quotient 7 as the next digit in the result. 
Result so far: 47004.49187
Subtract 3017 from 3420 to get 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Let's proceed to step 14:
The number 431 fits into 4030 9 times, leaving a remainder of 151.
The number 9 becomes the next digit in our result. 
Result so far: 47004.491879
Subtract 3879 from 4030 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

On to step 15:
If we divide 1510 by 431, we get 3 and a remainder of 217.
Record the quotient 3 as the next digit in the result. 
Result so far: 47004.4918793
The remainder is 217 after subtracting 1293 from 1510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Step 16:
2170 divided by 431 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 47004.49187935
Subtract 2155 from 2170 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.

The quotient of the division is 47004.49187935, and the remainder is 1.5e-08.
