We look at the division of 189851 by 43 
Our goal is to divide 189851 by 43.

Advancing to step 1:
If we divide 1 by 43, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 43

Step 2:
The number 43 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 43

Step 3:
The number 43 fits into 189 4 times, leaving a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 172 from 189 to get 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 43

Advancing to step 4:
If we divide 178 by 43, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 172 away from 178, we end up with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 43

Advancing to step 5:
43 can be fit into 65 1 times, resulting in a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 441.0
If we take 43 away from 65, we end up with 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 43

Advancing to step 6:
The number 43 fits into 221 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 4415.0
Subtract 215 from 221 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
43 goes into 60 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 4415.1
If we subtract 43 from 60, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 8:
43 can be fit into 170 3 times, resulting in a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 4415.13
Subtract 129 from 170 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
410 divided by 43 is 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 4415.139
Subtracting 387 from 410 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
43 goes into 230 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 4415.1395
The remainder is 15 after subtracting 215 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
43 can be fit into 150 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 4415.13953
Subtracting 129 from 150 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 12:
The number 43 fits into 210 4 times, leaving a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 4415.139534
Subtracting 172 from 210 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
If we divide 380 by 43, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 4415.1395348
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
43 can be fit into 360 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 4415.13953488
Deduct 344 from 360 and we're left 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.

The final result is 4415.13953488 with a remainder of 1.6e-08.
