Let's divide 90360015 by 857
Our goal is to divide 90360015 by 857.

Moving on to step 1:
If we divide 9 by 857, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
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 / 857

Step 2:
857 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 857

Let's proceed to step 3:
903 divided by 857 is 1 with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 857 away from 903, we end up with 46.
Take the next digit (6) from the dividend and append it to 46, then repeat: 466 / 857

Step 4:
857 can be fit into 466 0 times, resulting in a remainder of 466.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 466, we get 466.
Bring next digit (0) of the dividend behind the 466 and repeat the process: 4660 / 857

Advancing to step 5:
857 goes into 4660 5 times with a remainder of 375.
The next digit of our result is 5. 
Result so far: 105.0
The remainder is 375 after subtracting 4285 from 4660.
Fetch the next digit (0) from the dividend, attach it to 375 and continue: 3750 / 857

Moving on to step 6:
The number 857 fits into 3750 4 times, leaving a remainder of 322.
Put 4 as the next digit of the answer. 
Result so far: 1054.0
If we subtract 3428 from 3750, we get 322.
Bring next digit (1) of the dividend behind the 322 and repeat the process: 3221 / 857

Let's proceed to step 7:
857 can be fit into 3221 3 times, resulting in a remainder of 650.
Record the quotient 3 as the next digit in the result. 
Result so far: 10543.0
If we take 2571 away from 3221, we end up with 650.
Take the next digit (5) from the dividend and append it to 650, then repeat: 6505 / 857

Let's proceed to step 8:
857 goes into 6505 7 times with a remainder of 506.
Put 7 as the next digit of the answer. 
Result so far: 105437.0
The remainder is 506 after subtracting 5999 from 6505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Step 9:
The number 857 fits into 5060 5 times, leaving a remainder of 775.
The number 5 becomes the next digit in our result. 
Result so far: 105437.5
If we subtract 4285 from 5060, we get 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Going ahead to step 10:
857 can be fit into 7750 9 times, resulting in a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 105437.59
Deduct 7713 from 7750 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 11:
857 goes into 370 0 times with a remainder of 370.
The next digit of our result is 0. 
Result so far: 105437.59
Deduct 0 from 370 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 12:
When dividing 3700 by 857, we get 4 with a remainder of 272.
The number 4 becomes the next digit in our result. 
Result so far: 105437.5904
Subtract 3428 from 3700 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 13:
If we divide 2720 by 857, we get 3 and a remainder of 149.
Put 3 as the next digit of the answer. 
Result so far: 105437.59043
If we take 2571 away from 2720, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 14:
857 goes into 1490 1 times with a remainder of 633.
The next digit of our result is 1. 
Result so far: 105437.590431
Deduct 857 from 1490 and we're left with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Advancing to step 15:
6330 divided by 857 is 7 with a remainder of 331.
Use 7 as the next digit of our solution. 
Result so far: 105437.5904317
The remainder is 331 after subtracting 5999 from 6330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Let's proceed to step 16:
3310 divided by 857 is 3 with a remainder of 739.
The next digit of our result is 3. 
Result so far: 105437.59043173
The remainder is 739 after subtracting 2571 from 3310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

The final result is 105437.59043173 with a remainder of 7.39e-07.
