90685448 divided by 86 
Our goal is to divide 90685448 by 86.

Let's proceed to step 1:
86 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 86

Step 2:
86 goes into 90 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 4 after subtracting 86 from 90.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 86

On to step 3:
46 divided by 86 is 0 with a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 46, we end up with 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 86

Going ahead to step 4:
The number 86 fits into 468 5 times, leaving a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 105.0
If we take 430 away from 468, we end up with 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 86

Let's proceed to step 5:
86 can be fit into 385 4 times, resulting in a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 1054.0
If we subtract 344 from 385, we get 41.
Fetch the next digit (4) from the dividend, attach it to 41 and continue: 414 / 86

Going ahead to step 6:
The number 86 fits into 414 4 times, leaving a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 10544.0
Subtract 344 from 414 to get 70.
Take the next digit (4) from the dividend and append it to 70, then repeat: 704 / 86

Let's proceed to step 7:
704 divided by 86 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 105448.0
Subtracting 688 from 704 leaves us with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 86

Going ahead to step 8:
86 can be fit into 168 1 times, resulting in a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 1054481.0
The remainder is 82 after subtracting 86 from 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 9:
820 divided by 86 is 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 1054481.9
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
86 can be fit into 460 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 1054481.95
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 1054481.953
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
When dividing 420 by 86, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 1054481.9534
If we take 344 away from 420, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 13:
86 goes into 760 8 times with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 1054481.95348
If we take 688 away from 760, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
If we divide 720 by 86, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 1054481.953488
If we subtract 688 from 720, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 1054481.953488, with a leftover of 3.2e-06.
