We look at the division of 90659500 by 858 
We want to figure out the number of times 90659500 can be divided by 858.

Going ahead to step 1:
9 divided by 858 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 858

Step 2:
858 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Take the next digit (6) from the dividend and append it to 90, then repeat: 906 / 858

Advancing to step 3:
The number 858 fits into 906 1 times, leaving a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 858 away from 906, we end up with 48.
Grab the next digit (5) from the dividend, add it to 48, then carry on: 485 / 858

Advancing to step 4:
858 can be fit into 485 0 times, resulting in a remainder of 485.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 485 to get 485.
Include the next digit (9) from the dividend after 485, then repeat: 4859 / 858

Advancing to step 5:
If we divide 4859 by 858, we get 5 and a remainder of 569.
Use 5 as the next digit of our solution. 
Result so far: 105.0
If we take 4290 away from 4859, we end up with 569.
Include the next digit (5) from the dividend after 569, then repeat: 5695 / 858

On to step 6:
The number 858 fits into 5695 6 times, leaving a remainder of 547.
The next digit of our result is 6. 
Result so far: 1056.0
Deduct 5148 from 5695 and we're left with 547.
Append the next digit (0) from the dividend to 547 and continue with: 5470 / 858

Step 7:
858 can be fit into 5470 6 times, resulting in a remainder of 322.
Put 6 as the next digit of the answer. 
Result so far: 10566.0
If we subtract 5148 from 5470, we get 322.
Bring next digit (0) of the dividend behind the 322 and repeat the process: 3220 / 858

On to step 8:
858 goes into 3220 3 times with a remainder of 646.
Put 3 as the next digit of the answer. 
Result so far: 105663.0
If we subtract 2574 from 3220, we get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Step 9:
The number 858 fits into 6460 7 times, leaving a remainder of 454.
Use 7 as the next digit of our solution. 
Result so far: 105663.7
If we take 6006 away from 6460, we end up with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Going ahead to step 10:
4540 divided by 858 is 5 with a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 105663.75
The remainder is 250 after subtracting 4290 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 11:
When dividing 2500 by 858, we get 2 with a remainder of 784.
The number 2 becomes the next digit in our result. 
Result so far: 105663.752
The remainder is 784 after subtracting 1716 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Step 12:
The number 858 fits into 7840 9 times, leaving a remainder of 118.
The next digit of our result is 9. 
Result so far: 105663.7529
If we take 7722 away from 7840, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 13:
When dividing 1180 by 858, we get 1 with a remainder of 322.
The number 1 becomes the next digit in our result. 
Result so far: 105663.75291
Subtracting 858 from 1180 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 14:
If we divide 3220 by 858, we get 3 and a remainder of 646.
Put 3 as the next digit of the answer. 
Result so far: 105663.752913
Subtract 2574 from 3220 to get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

On to step 15:
If we divide 6460 by 858, we get 7 and a remainder of 454.
The number 7 becomes the next digit in our result. 
Result so far: 105663.7529137
If we take 6006 away from 6460, we end up with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Advancing to step 16:
4540 divided by 858 is 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 105663.75291375
Subtract 4290 from 4540 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final outcome is 105663.75291375, with a leftover of 2.5e-07.
