Let's divide 42201905 by 270
Let's see how many times 270 fits into 42201905.

On to step 1:
The number 270 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 270

Moving on to step 2:
The number 270 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
If we subtract 0 from 42, we get 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 270

Advancing to step 3:
270 goes into 422 1 times with a remainder of 152.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 270 away from 422, we end up with 152.
Take the next digit (0) from the dividend and append it to 152, then repeat: 1520 / 270

Moving on to step 4:
270 goes into 1520 5 times with a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 1350 from 1520 to get 170.
Take the next digit (1) from the dividend and append it to 170, then repeat: 1701 / 270

Going ahead to step 5:
1701 divided by 270 is 6 with a remainder of 81.
Use 6 as the next digit of our solution. 
Result so far: 156.0
Subtract 1620 from 1701 to get 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 270

On to step 6:
When dividing 819 by 270, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 1563.0
Deduct 810 from 819 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 270

Advancing to step 7:
270 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 15630.0
If we take 0 away from 90, we end up with 90.
Bring next digit (5) of the dividend behind the 90 and repeat the process: 905 / 270

Going ahead to step 8:
270 can be fit into 905 3 times, resulting in a remainder of 95.
The number 3 becomes the next digit in our result. 
Result so far: 156303.0
Deduct 810 from 905 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 9:
270 goes into 950 3 times with a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 156303.3
The remainder is 140 after subtracting 810 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
If we divide 1400 by 270, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 156303.35
If we take 1350 away from 1400, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
270 can be fit into 500 1 times, resulting in a remainder of 230.
Put 1 as the next digit of the answer. 
Result so far: 156303.351
Subtracting 270 from 500 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 12:
270 goes into 2300 8 times with a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 156303.3518
If we subtract 2160 from 2300, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 13:
If we divide 1400 by 270, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 156303.35185
If we take 1350 away from 1400, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
If we divide 500 by 270, we get 1 and a remainder of 230.
The next digit of our result is 1. 
Result so far: 156303.351851
If we take 270 away from 500, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 15:
When dividing 2300 by 270, we get 8 with a remainder of 140.
Put 8 as the next digit of the answer. 
Result so far: 156303.3518518
The remainder is 140 after subtracting 2160 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 16:
If we divide 1400 by 270, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 156303.35185185
Subtracting 1350 from 1400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 156303.35185185 with a remainder of 5e-08.
