We look at the division of 198103 by 43 
Let's see how many times 43 fits into 198103.

Advancing to step 1:
43 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 43

Step 2:
When dividing 19 by 43, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 43

On to step 3:
198 divided by 43 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 26 after subtracting 172 from 198.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 43

Advancing to step 4:
43 goes into 261 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtract 258 from 261 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 43

Going ahead to step 5:
30 divided by 43 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 460.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 43

Step 6:
The number 43 fits into 303 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 4607.0
Deduct 301 from 303 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
43 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 4607.0
Subtract 0 from 20 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.

Moving on to step 8:
The number 43 fits into 200 4 times, leaving a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 4607.04
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
43 goes into 280 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 4607.046
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 10:
43 goes into 220 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 4607.0465
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.

Step 11:
When dividing 50 by 43, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 4607.04651
Subtract 43 from 50 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
43 can be fit into 70 1 times, resulting in a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 4607.046511
Deduct 43 from 70 and we're left 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 4607.046511, with a leftover of 2.7e-06.
