Let's divide 42203009 by 202
We want to divide 42203009 by 202.

Advancing to step 1:
4 divided by 202 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 202

Step 2:
The number 202 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 202

Advancing to step 3:
202 goes into 422 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 18 after subtracting 404 from 422.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 202

Moving on to step 4:
If we divide 180 by 202, we get 0 and a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 180, we get 180.
Include the next digit (3) from the dividend after 180, then repeat: 1803 / 202

On to step 5:
202 can be fit into 1803 8 times, resulting in a remainder of 187.
The number 8 becomes the next digit in our result. 
Result so far: 208.0
If we take 1616 away from 1803, we end up with 187.
Take the next digit (0) from the dividend and append it to 187, then repeat: 1870 / 202

Going ahead to step 6:
202 can be fit into 1870 9 times, resulting in a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 2089.0
Subtracting 1818 from 1870 leaves us with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 202

Let's proceed to step 7:
The number 202 fits into 520 2 times, leaving a remainder of 116.
The next digit of our result is 2. 
Result so far: 20892.0
If we take 404 away from 520, we end up with 116.
Bring next digit (9) of the dividend behind the 116 and repeat the process: 1169 / 202

On to step 8:
If we divide 1169 by 202, we get 5 and a remainder of 159.
Write down 5 as next digit of the result. 
Result so far: 208925.0
If we take 1010 away from 1169, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Let's proceed to step 9:
When dividing 1590 by 202, we get 7 with a remainder of 176.
Write down 7 as next digit of the result. 
Result so far: 208925.7
Subtracting 1414 from 1590 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 10:
202 goes into 1760 8 times with a remainder of 144.
The next digit of our result is 8. 
Result so far: 208925.78
Deduct 1616 from 1760 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 11:
202 can be fit into 1440 7 times, resulting in a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 208925.787
The remainder is 26 after subtracting 1414 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
260 divided by 202 is 1 with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 208925.7871
Subtract 202 from 260 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
202 goes into 580 2 times with a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 208925.78712
If we take 404 away from 580, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 14:
1760 divided by 202 is 8 with a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 208925.787128
If we subtract 1616 from 1760, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 15:
202 goes into 1440 7 times with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 208925.7871287
If we take 1414 away from 1440, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 16:
202 goes into 260 1 times with a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 208925.78712871
If we take 202 away from 260, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 208925.78712871, with a leftover of 5.8e-08.
