43038198 ÷ 102 
We want to figure out the number of times 43038198 can be divided by 102.

Going ahead to step 1:
4 divided by 102 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 102

Let's proceed to step 2:
102 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 102

On to step 3:
If we divide 430 by 102, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 408 from 430 leaves us with 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 102

Let's proceed to step 4:
102 goes into 223 2 times with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we subtract 204 from 223, we get 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 102

Step 5:
102 goes into 198 1 times with a remainder of 96.
Write down 1 as next digit of the result. 
Result so far: 421.0
The remainder is 96 after subtracting 102 from 198.
Bring next digit (1) of the dividend behind the 96 and repeat the process: 961 / 102

Advancing to step 6:
If we divide 961 by 102, we get 9 and a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 4219.0
Subtract 918 from 961 to get 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 102

Step 7:
102 can be fit into 439 4 times, resulting in a remainder of 31.
The next digit of our result is 4. 
Result so far: 42194.0
Subtracting 408 from 439 leaves us with 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 102

Let's proceed to step 8:
If we divide 318 by 102, we get 3 and a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 421943.0
Subtracting 306 from 318 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 102 fits into 120 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 421943.1
The remainder is 18 after subtracting 102 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
When dividing 180 by 102, we get 1 with a remainder of 78.
Put 1 as the next digit of the answer. 
Result so far: 421943.11
Deduct 102 from 180 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final outcome is 421943.11, with a leftover of 0.078.
