43552855 ÷ 102 
We want to figure out the number of times 43552855 can be divided by 102.

On to step 1:
The number 102 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 102

Let's proceed to step 2:
102 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 102

Let's proceed to step 3:
102 can be fit into 435 4 times, resulting in a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 27 after subtracting 408 from 435.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 102

Moving on to step 4:
The number 102 fits into 275 2 times, leaving a remainder of 71.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 204 from 275 leaves us with 71.
Fetch the next digit (2) from the dividend, attach it to 71 and continue: 712 / 102

Step 5:
102 goes into 712 6 times with a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 426.0
If we take 612 away from 712, we end up with 100.
Fetch the next digit (8) from the dividend, attach it to 100 and continue: 1008 / 102

Let's proceed to step 6:
When dividing 1008 by 102, we get 9 with a remainder of 90.
Put 9 as the next digit of the answer. 
Result so far: 4269.0
The remainder is 90 after subtracting 918 from 1008.
Take the next digit (5) from the dividend and append it to 90, then repeat: 905 / 102

Advancing to step 7:
102 goes into 905 8 times with a remainder of 89.
Record the quotient 8 as the next digit in the result. 
Result so far: 42698.0
Deduct 816 from 905 and we're left with 89.
Take the next digit (5) from the dividend and append it to 89, then repeat: 895 / 102

Let's proceed to step 8:
If we divide 895 by 102, we get 8 and a remainder of 79.
Put 8 as the next digit of the answer. 
Result so far: 426988.0
If we subtract 816 from 895, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 9:
102 goes into 790 7 times with a remainder of 76.
Record the quotient 7 as the next digit in the result. 
Result so far: 426988.7
Subtract 714 from 790 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
760 divided by 102 is 7 with a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 426988.77
Subtracting 714 from 760 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 426988.77, and the remainder is 0.046.
