We're dividing 88857159 by 523 
Let's see how many times 523 fits into 88857159.

On to step 1:
The number 523 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 523

Let's proceed to step 2:
523 goes into 88 0 times with a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Fetch the next digit (8) from the dividend, attach it to 88 and continue: 888 / 523

Going ahead to step 3:
523 can be fit into 888 1 times, resulting in a remainder of 365.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 365 after subtracting 523 from 888.
Fetch the next digit (5) from the dividend, attach it to 365 and continue: 3655 / 523

Moving on to step 4:
The number 523 fits into 3655 6 times, leaving a remainder of 517.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 3138 from 3655 and we're left with 517.
Take the next digit (7) from the dividend and append it to 517, then repeat: 5177 / 523

On to step 5:
523 goes into 5177 9 times with a remainder of 470.
The next digit of our result is 9. 
Result so far: 169.0
Deduct 4707 from 5177 and we're left with 470.
Bring next digit (1) of the dividend behind the 470 and repeat the process: 4701 / 523

Advancing to step 6:
523 goes into 4701 8 times with a remainder of 517.
Use 8 as the next digit of our solution. 
Result so far: 1698.0
Deduct 4184 from 4701 and we're left with 517.
Take the next digit (5) from the dividend and append it to 517, then repeat: 5175 / 523

On to step 7:
523 can be fit into 5175 9 times, resulting in a remainder of 468.
The number 9 becomes the next digit in our result. 
Result so far: 16989.0
Deduct 4707 from 5175 and we're left with 468.
Fetch the next digit (9) from the dividend, attach it to 468 and continue: 4689 / 523

Step 8:
The number 523 fits into 4689 8 times, leaving a remainder of 505.
Put 8 as the next digit of the answer. 
Result so far: 169898.0
Deduct 4184 from 4689 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Moving on to step 9:
523 can be fit into 5050 9 times, resulting in a remainder of 343.
Put 9 as the next digit of the answer. 
Result so far: 169898.9
Subtract 4707 from 5050 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 10:
The number 523 fits into 3430 6 times, leaving a remainder of 292.
Use 6 as the next digit of our solution. 
Result so far: 169898.96
The remainder is 292 after subtracting 3138 from 3430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 11:
If we divide 2920 by 523, we get 5 and a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 169898.965
If we take 2615 away from 2920, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 12:
523 goes into 3050 5 times with a remainder of 435.
The number 5 becomes the next digit in our result. 
Result so far: 169898.9655
Subtract 2615 from 3050 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

The final outcome is 169898.9655, with a leftover of 0.00435.
