We divide 66175978 by 220
Our goal is to divide 66175978 by 220.

On to step 1:
6 divided by 220 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 220

Step 2:
220 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 220

On to step 3:
661 divided by 220 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 660 from 661 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 220

Moving on to step 4:
220 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we take 0 away from 17, we end up with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 220

Step 5:
220 can be fit into 175 0 times, resulting in a remainder of 175.
Put 0 as the next digit of the answer. 
Result so far: 300.0
If we take 0 away from 175, we end up with 175.
Take the next digit (9) from the dividend and append it to 175, then repeat: 1759 / 220

Step 6:
220 goes into 1759 7 times with a remainder of 219.
The number 7 becomes the next digit in our result. 
Result so far: 3007.0
Subtract 1540 from 1759 to get 219.
Fetch the next digit (7) from the dividend, attach it to 219 and continue: 2197 / 220

Step 7:
2197 divided by 220 is 9 with a remainder of 217.
Use 9 as the next digit of our solution. 
Result so far: 30079.0
If we take 1980 away from 2197, we end up with 217.
Include the next digit (8) from the dividend after 217, then repeat: 2178 / 220

Moving on to step 8:
220 can be fit into 2178 9 times, resulting in a remainder of 198.
Write down 9 as next digit of the result. 
Result so far: 300799.0
Subtracting 1980 from 2178 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 9:
When dividing 1980 by 220, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 300799.9
Subtract 1980 from 1980 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 220, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 300799.9
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
220 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 300799.9
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 300799.9, and the remainder is 0.0.
