We divide 785521 by 86
We want to divide 785521 by 86.

Moving on to step 1:
The number 86 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 86

Going ahead to step 2:
If we divide 78 by 86, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 86

On to step 3:
The number 86 fits into 785 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 11 after subtracting 774 from 785.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 86

Step 4:
86 can be fit into 115 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 91.0
The remainder is 29 after subtracting 86 from 115.
Take the next digit (2) from the dividend and append it to 29, then repeat: 292 / 86

On to step 5:
The number 86 fits into 292 3 times, leaving a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 913.0
Deduct 258 from 292 and we're left with 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 86

Step 6:
If we divide 341 by 86, we get 3 and a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 9133.0
If we subtract 258 from 341, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 7:
The number 86 fits into 830 9 times, leaving a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 9133.9
Subtract 774 from 830 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
86 can be fit into 560 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 9133.96
Deduct 516 from 560 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
The number 86 fits into 440 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 9133.965
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
86 can be fit into 100 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 9133.9651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
86 can be fit into 140 1 times, resulting in a remainder of 54.
The next digit of our result is 1. 
Result so far: 9133.96511
If we subtract 86 from 140, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 9133.96511, with a leftover of 5.4e-05.
