We're dividing 86795759 by 431 
Our goal is to divide 86795759 by 431.

On to step 1:
431 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 431

On to step 2:
If we divide 86 by 431, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (7) from the dividend and append it to 86, then repeat: 867 / 431

Advancing to step 3:
The number 431 fits into 867 2 times, leaving a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 862 from 867 leaves us with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 431

On to step 4:
When dividing 59 by 431, we get 0 with a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 59 after subtracting 0 from 59.
Fetch the next digit (5) from the dividend, attach it to 59 and continue: 595 / 431

Advancing to step 5:
431 goes into 595 1 times with a remainder of 164.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
Subtract 431 from 595 to get 164.
Bring next digit (7) of the dividend behind the 164 and repeat the process: 1647 / 431

On to step 6:
When dividing 1647 by 431, we get 3 with a remainder of 354.
Write down 3 as next digit of the result. 
Result so far: 2013.0
If we subtract 1293 from 1647, we get 354.
Take the next digit (5) from the dividend and append it to 354, then repeat: 3545 / 431

Step 7:
When dividing 3545 by 431, we get 8 with a remainder of 97.
Record the quotient 8 as the next digit in the result. 
Result so far: 20138.0
If we subtract 3448 from 3545, we get 97.
Include the next digit (9) from the dividend after 97, then repeat: 979 / 431

Going ahead to step 8:
The number 431 fits into 979 2 times, leaving a remainder of 117.
Put 2 as the next digit of the answer. 
Result so far: 201382.0
Subtracting 862 from 979 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 9:
The number 431 fits into 1170 2 times, leaving a remainder of 308.
Use 2 as the next digit of our solution. 
Result so far: 201382.2
If we take 862 away from 1170, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 10:
3080 divided by 431 is 7 with a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 201382.27
If we take 3017 away from 3080, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 11:
630 divided by 431 is 1 with a remainder of 199.
Put 1 as the next digit of the answer. 
Result so far: 201382.271
Subtracting 431 from 630 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 12:
When dividing 1990 by 431, we get 4 with a remainder of 266.
The number 4 becomes the next digit in our result. 
Result so far: 201382.2714
The remainder is 266 after subtracting 1724 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 13:
The number 431 fits into 2660 6 times, leaving a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 201382.27146
Deduct 2586 from 2660 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 14:
The number 431 fits into 740 1 times, leaving a remainder of 309.
Record the quotient 1 as the next digit in the result. 
Result so far: 201382.271461
Subtract 431 from 740 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Advancing to step 15:
If we divide 3090 by 431, we get 7 and a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 201382.2714617
Deduct 3017 from 3090 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 16:
The number 431 fits into 730 1 times, leaving a remainder of 299.
Use 1 as the next digit of our solution. 
Result so far: 201382.27146171
If we subtract 431 from 730, we get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

The final outcome is 201382.27146171, with a leftover of 2.99e-07.
