Let's divide 42399975 by 203
Our goal is to divide 42399975 by 203.

On to step 1:
4 divided by 203 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 203

Moving on to step 2:
The number 203 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 203

Let's proceed to step 3:
203 can be fit into 423 2 times, resulting in a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 406 away from 423, we end up with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 203

Advancing to step 4:
203 can be fit into 179 0 times, resulting in a remainder of 179.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 179, we end up with 179.
Append the next digit (9) from the dividend to 179 and continue with: 1799 / 203

Moving on to step 5:
203 can be fit into 1799 8 times, resulting in a remainder of 175.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
If we subtract 1624 from 1799, we get 175.
Take the next digit (9) from the dividend and append it to 175, then repeat: 1759 / 203

Moving on to step 6:
If we divide 1759 by 203, we get 8 and a remainder of 135.
Put 8 as the next digit of the answer. 
Result so far: 2088.0
Deduct 1624 from 1759 and we're left with 135.
Grab the next digit (7) from the dividend, add it to 135, then carry on: 1357 / 203

Let's proceed to step 7:
When dividing 1357 by 203, we get 6 with a remainder of 139.
Use 6 as the next digit of our solution. 
Result so far: 20886.0
Subtract 1218 from 1357 to get 139.
Take the next digit (5) from the dividend and append it to 139, then repeat: 1395 / 203

Going ahead to step 8:
The number 203 fits into 1395 6 times, leaving a remainder of 177.
Record the quotient 6 as the next digit in the result. 
Result so far: 208866.0
Subtracting 1218 from 1395 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Advancing to step 9:
If we divide 1770 by 203, we get 8 and a remainder of 146.
Put 8 as the next digit of the answer. 
Result so far: 208866.8
If we subtract 1624 from 1770, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 10:
The number 203 fits into 1460 7 times, leaving a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 208866.87
Deduct 1421 from 1460 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
203 goes into 390 1 times with a remainder of 187.
Record the quotient 1 as the next digit in the result. 
Result so far: 208866.871
If we take 203 away from 390, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 12:
If we divide 1870 by 203, we get 9 and a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 208866.8719
The remainder is 43 after subtracting 1827 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 13:
The number 203 fits into 430 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 208866.87192
Subtracting 406 from 430 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
203 goes into 240 1 times with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 208866.871921
The remainder is 37 after subtracting 203 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 15:
The number 203 fits into 370 1 times, leaving a remainder of 167.
Use 1 as the next digit of our solution. 
Result so far: 208866.8719211
Subtract 203 from 370 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

In conclusion, the division gives 208866.8719211 with a balance of 1.67e-06.
