We're dividing 80980251 by 43 
We want to divide 80980251 by 43.

Moving on to step 1:
43 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 43

Step 2:
43 can be fit into 80 1 times, resulting in a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 43 from 80 leaves us with 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 43

Moving on to step 3:
The number 43 fits into 379 8 times, leaving a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 344 from 379 leaves us with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 43

Moving on to step 4:
43 can be fit into 358 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
The remainder is 14 after subtracting 344 from 358.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 43

Advancing to step 5:
The number 43 fits into 140 3 times, leaving a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 1883.0
Subtract 129 from 140 to get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 43

Step 6:
43 goes into 112 2 times with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 18832.0
If we subtract 86 from 112, we get 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 43

On to step 7:
If we divide 265 by 43, we get 6 and a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 188326.0
The remainder is 7 after subtracting 258 from 265.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 43

Going ahead to step 8:
71 divided by 43 is 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1883261.0
Deduct 43 from 71 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
The number 43 fits into 280 6 times, leaving a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 1883261.6
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
When dividing 220 by 43, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1883261.65
Subtracting 215 from 220 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
If we divide 50 by 43, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1883261.651
Subtracting 43 from 50 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
70 divided by 43 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1883261.6511
Deduct 43 from 70 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 1883261.6511 with a remainder of 0.00027.
