84642863 ÷ 43 
We want to divide 84642863 by 43.

Step 1:
When dividing 8 by 43, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 43

Advancing to step 2:
When dividing 84 by 43, we get 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 43 from 84 and we're left with 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 43

On to step 3:
If we divide 416 by 43, we get 9 and a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 29 after subtracting 387 from 416.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 43

Let's proceed to step 4:
294 divided by 43 is 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
If we take 258 away from 294, we end up with 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 43

On to step 5:
362 divided by 43 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 1968.0
Subtract 344 from 362 to get 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 43

Moving on to step 6:
If we divide 188 by 43, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 19684.0
The remainder is 16 after subtracting 172 from 188.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 43

Step 7:
The number 43 fits into 166 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 196843.0
If we take 129 away from 166, we end up with 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 43

Going ahead to step 8:
If we divide 373 by 43, we get 8 and a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 1968438.0
If we take 344 away from 373, 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.

On to step 9:
43 can be fit into 290 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 1968438.6
Subtracting 258 from 290 leaves us 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.

Moving on to step 10:
43 goes into 320 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 1968438.67
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 11:
If we divide 190 by 43, we get 4 and a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 1968438.674
If we take 172 away from 190, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
43 can be fit into 180 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 1968438.6744
The remainder is 8 after subtracting 172 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 1968438.6744 with a balance of 8e-05.
