80392198 ÷ 43 
We want to figure out the number of times 80392198 can be divided by 43.

Going ahead to step 1:
If we divide 8 by 43, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 43

On to step 2:
43 can be fit into 80 1 times, resulting in a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 43 from 80 and we're left with 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 43

Step 3:
43 goes into 373 8 times with a remainder of 29.
The next digit of our result is 8. 
Result so far: 18.0
If we take 344 away from 373, we end up with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 43

Advancing to step 4:
If we divide 299 by 43, we get 6 and a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 186.0
Deduct 258 from 299 and we're left with 41.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 43

On to step 5:
43 goes into 412 9 times with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 1869.0
If we subtract 387 from 412, we get 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 43

Advancing to step 6:
43 goes into 251 5 times with a remainder of 36.
The next digit of our result is 5. 
Result so far: 18695.0
If we take 215 away from 251, we end up with 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 43

On to step 7:
369 divided by 43 is 8 with a remainder of 25.
The next digit of our result is 8. 
Result so far: 186958.0
The remainder is 25 after subtracting 344 from 369.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 43

Moving on to step 8:
258 divided by 43 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 1869586.0
If we subtract 258 from 258, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 43, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1869586.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 43, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1869586.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1869586.0 and a remainder of 0.0.
