We look at the division of 878870 by 43 
We want to divide 878870 by 43.

Going ahead to step 1:
43 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 43

Advancing to step 2:
43 goes into 87 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 1 after subtracting 86 from 87.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 43

Step 3:
When dividing 18 by 43, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 43

Going ahead to step 4:
43 goes into 188 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
Subtracting 172 from 188 leaves us with 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 43

On to step 5:
167 divided by 43 is 3 with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 2043.0
If we subtract 129 from 167, we get 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 43

On to step 6:
43 goes into 380 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 20438.0
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
43 can be fit into 360 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 20438.8
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
When dividing 160 by 43, we get 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 20438.83
If we take 129 away from 160, we end up 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.

On to step 9:
43 goes into 310 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 20438.837
Subtract 301 from 310 to get 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 10:
The number 43 fits into 90 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 20438.8372
If we take 86 away from 90, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
43 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 20438.8372
If we subtract 0 from 40, we 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.

Advancing to step 12:
43 goes into 400 9 times with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 20438.837209
The remainder is 13 after subtracting 387 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
If we divide 130 by 43, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 20438.8372093
If we subtract 129 from 130, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
10 divided by 43 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 20438.8372093
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 20438.8372093 and a remainder of 1e-08.
