We look at the division of 89521218 by 724 
Let's see how many times 724 fits into 89521218.

Going ahead to step 1:
8 divided by 724 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 724

Step 2:
89 divided by 724 is 0 with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Take the next digit (5) from the dividend and append it to 89, then repeat: 895 / 724

Let's proceed to step 3:
If we divide 895 by 724, we get 1 and a remainder of 171.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 171 after subtracting 724 from 895.
Fetch the next digit (2) from the dividend, attach it to 171 and continue: 1712 / 724

Going ahead to step 4:
The number 724 fits into 1712 2 times, leaving a remainder of 264.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1448 from 1712 and we're left with 264.
Include the next digit (1) from the dividend after 264, then repeat: 2641 / 724

Moving on to step 5:
724 can be fit into 2641 3 times, resulting in a remainder of 469.
Put 3 as the next digit of the answer. 
Result so far: 123.0
If we subtract 2172 from 2641, we get 469.
Take the next digit (2) from the dividend and append it to 469, then repeat: 4692 / 724

Advancing to step 6:
The number 724 fits into 4692 6 times, leaving a remainder of 348.
Use 6 as the next digit of our solution. 
Result so far: 1236.0
The remainder is 348 after subtracting 4344 from 4692.
Grab the next digit (1) from the dividend, add it to 348, then carry on: 3481 / 724

On to step 7:
The number 724 fits into 3481 4 times, leaving a remainder of 585.
Record the quotient 4 as the next digit in the result. 
Result so far: 12364.0
The remainder is 585 after subtracting 2896 from 3481.
Grab the next digit (8) from the dividend, add it to 585, then carry on: 5858 / 724

Going ahead to step 8:
724 can be fit into 5858 8 times, resulting in a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 123648.0
If we subtract 5792 from 5858, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
The number 724 fits into 660 0 times, leaving a remainder of 660.
The next digit of our result is 0. 
Result so far: 123648.0
If we take 0 away from 660, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 10:
When dividing 6600 by 724, we get 9 with a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 123648.09
Deduct 6516 from 6600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
724 goes into 840 1 times with a remainder of 116.
The number 1 becomes the next digit in our result. 
Result so far: 123648.091
Subtract 724 from 840 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 12:
If we divide 1160 by 724, we get 1 and a remainder of 436.
Record the quotient 1 as the next digit in the result. 
Result so far: 123648.0911
Subtracting 724 from 1160 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

The quotient of the division is 123648.0911, and the remainder is 0.00436.
