Let's divide 87891321 by 55
Our goal is to divide 87891321 by 55.

Going ahead to step 1:
When dividing 8 by 55, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 55

Let's proceed to step 2:
The number 55 fits into 87 1 times, leaving a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 55 from 87 and we're left with 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 55

Advancing to step 3:
The number 55 fits into 328 5 times, leaving a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 275 from 328 and we're left with 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 55

Let's proceed to step 4:
If we divide 539 by 55, we get 9 and a remainder of 44.
The next digit of our result is 9. 
Result so far: 159.0
Subtract 495 from 539 to get 44.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 55

Step 5:
The number 55 fits into 441 8 times, leaving a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 1598.0
Subtracting 440 from 441 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 55

Step 6:
The number 55 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 15980.0
If we subtract 0 from 13, we get 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 55

Moving on to step 7:
The number 55 fits into 132 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 159802.0
Subtract 110 from 132 to get 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 55

Moving on to step 8:
221 divided by 55 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 1598024.0
Deduct 220 from 221 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
10 divided by 55 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 1598024.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
When dividing 100 by 55, we get 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 1598024.01
If we take 55 away from 100, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
55 can be fit into 450 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 1598024.018
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
100 divided by 55 is 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 1598024.0181
The remainder is 45 after subtracting 55 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
450 divided by 55 is 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 1598024.01818
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
55 goes into 100 1 times with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 1598024.018181
Subtracting 55 from 100 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 15:
55 goes into 450 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 1598024.0181818
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 16:
If we divide 100 by 55, we get 1 and a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 1598024.01818181
The remainder is 45 after subtracting 55 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 1598024.01818181 with a remainder of 4.5e-08.
