We divide 86858644 by 43
We're looking to find how many times 43 goes into 86858644.

Step 1:
43 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 43

Advancing to step 2:
The number 43 fits into 86 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 86 from 86 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 43

Advancing to step 3:
If we divide 8 by 43, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 43

Going ahead to step 4:
When dividing 85 by 43, we get 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
Deduct 43 from 85 and we're left with 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 43

Going ahead to step 5:
The number 43 fits into 428 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 2019.0
If we take 387 away from 428, we end up with 41.
Take the next digit (6) from the dividend and append it to 41, then repeat: 416 / 43

Step 6:
The number 43 fits into 416 9 times, leaving a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 20199.0
Deduct 387 from 416 and we're left with 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 43

On to step 7:
If we divide 294 by 43, we get 6 and a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 201996.0
Subtract 258 from 294 to get 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 43

Step 8:
When dividing 364 by 43, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 2019968.0
Subtract 344 from 364 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
The number 43 fits into 200 4 times, leaving a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 2019968.4
Deduct 172 from 200 and we're left 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.

Going ahead to step 10:
If we divide 280 by 43, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 2019968.46
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
220 divided by 43 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 2019968.465
If we take 215 away from 220, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
The number 43 fits into 50 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 2019968.4651
Subtracting 43 from 50 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
43 can be fit into 70 1 times, resulting in a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 2019968.46511
If we subtract 43 from 70, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 2019968.46511 and a remainder of 2.7e-05.
