We're dividing 421172 by 43 
Our goal is to divide 421172 by 43.

Let's proceed to step 1:
4 divided by 43 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 43

Moving on to step 2:
42 divided by 43 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 43

Step 3:
The number 43 fits into 421 9 times, leaving a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 387 from 421 to get 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 43

Step 4:
341 divided by 43 is 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Subtract 301 from 341 to get 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 43

Advancing to step 5:
43 can be fit into 407 9 times, resulting in a remainder of 20.
The next digit of our result is 9. 
Result so far: 979.0
Subtracting 387 from 407 leaves us with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 43

Advancing to step 6:
If we divide 202 by 43, we get 4 and a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 9794.0
Deduct 172 from 202 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
If we divide 300 by 43, we get 6 and a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 9794.6
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
43 goes into 420 9 times with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 9794.69
Deduct 387 from 420 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
When dividing 330 by 43, we get 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 9794.697
If we take 301 away from 330, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 10:
43 can be fit into 290 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 9794.6976
Deduct 258 from 290 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
320 divided by 43 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 9794.69767
Deduct 301 from 320 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
43 can be fit into 190 4 times, resulting in a remainder of 18.
The next digit of our result is 4. 
Result so far: 9794.697674
If we subtract 172 from 190, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
The number 43 fits into 180 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 9794.6976744
Subtract 172 from 180 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 9794.6976744, and the remainder is 8e-08.
