3994129 divided by 43 
Our goal is to divide 3994129 by 43.

Step 1:
43 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 43

Going ahead to step 2:
43 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 43

Advancing to step 3:
43 can be fit into 399 9 times, resulting in a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 387 away from 399, we end up with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 43

Moving on to step 4:
If we divide 124 by 43, we get 2 and a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 92.0
The remainder is 38 after subtracting 86 from 124.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 43

Going ahead to step 5:
381 divided by 43 is 8 with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 928.0
If we subtract 344 from 381, we get 37.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 43

Moving on to step 6:
When dividing 372 by 43, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 9288.0
If we take 344 away from 372, we end up with 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 43

Going ahead to step 7:
289 divided by 43 is 6 with a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 92886.0
Subtracting 258 from 289 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 8:
If we divide 310 by 43, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 92886.7
Deduct 301 from 310 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
The number 43 fits into 90 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 92886.72
If we subtract 86 from 90, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
40 divided by 43 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 92886.72
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
If we divide 400 by 43, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 92886.7209
If we subtract 387 from 400, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
The number 43 fits into 130 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 92886.72093
The remainder is 1 after subtracting 129 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
43 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 92886.72093
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
43 goes into 100 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 92886.7209302
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 15:
If we divide 140 by 43, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 92886.72093023
Subtract 129 from 140 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 92886.72093023 with a remainder of 1.1e-08.
