42177 divided by 43 
Let's see how many times 43 fits into 42177.

Going ahead to step 1:
4 divided by 43 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 43

Moving on to step 2:
If we divide 42 by 43, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 43

Going ahead to step 3:
43 goes into 421 9 times with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 387 away from 421, we end up with 34.
Take the next digit (7) from the dividend and append it to 34, then repeat: 347 / 43

Advancing to step 4:
If we divide 347 by 43, we get 8 and a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we take 344 away from 347, we end up with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 43

Advancing to step 5:
43 goes into 37 0 times with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 980.0
Subtract 0 from 37 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 6:
43 can be fit into 370 8 times, resulting in a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 980.8
Subtracting 344 from 370 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
When dividing 260 by 43, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 980.86
Subtract 258 from 260 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
If we divide 20 by 43, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 980.86
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 43, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 980.8604
If we take 172 away from 200, we end up 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.

Step 10:
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: 980.86046
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.

Moving on to step 11:
If we divide 220 by 43, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 980.860465
If we subtract 215 from 220, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
43 goes into 50 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 980.8604651
The remainder is 7 after subtracting 43 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
The number 43 fits into 70 1 times, leaving a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 980.86046511
Subtracting 43 from 70 leaves us 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 outcome is 980.86046511, with a leftover of 2.7e-08.
