68173094 divided by 220 
Our goal is to divide 68173094 by 220.

Advancing to step 1:
When dividing 6 by 220, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 220

Let's proceed to step 2:
220 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 220

Let's proceed to step 3:
220 goes into 681 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 21 after subtracting 660 from 681.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 220

On to step 4:
220 goes into 217 0 times with a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 217 and we're left with 217.
Include the next digit (3) from the dividend after 217, then repeat: 2173 / 220

On to step 5:
If we divide 2173 by 220, we get 9 and a remainder of 193.
The next digit of our result is 9. 
Result so far: 309.0
If we subtract 1980 from 2173, we get 193.
Fetch the next digit (0) from the dividend, attach it to 193 and continue: 1930 / 220

Going ahead to step 6:
The number 220 fits into 1930 8 times, leaving a remainder of 170.
The number 8 becomes the next digit in our result. 
Result so far: 3098.0
If we subtract 1760 from 1930, we get 170.
Include the next digit (9) from the dividend after 170, then repeat: 1709 / 220

Advancing to step 7:
The number 220 fits into 1709 7 times, leaving a remainder of 169.
Use 7 as the next digit of our solution. 
Result so far: 30987.0
If we subtract 1540 from 1709, we get 169.
Append the next digit (4) from the dividend to 169 and continue with: 1694 / 220

Let's proceed to step 8:
220 goes into 1694 7 times with a remainder of 154.
Put 7 as the next digit of the answer. 
Result so far: 309877.0
Subtract 1540 from 1694 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 9:
If we divide 1540 by 220, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 309877.7
Subtract 1540 from 1540 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.

Moving on to step 10:
220 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 309877.7
If we take 0 away from 0, we end up 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.
Use 0 as the next digit of our solution. 
Result so far: 309877.7
If we take 0 away from 0, we end up 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.

Our division results in 309877.7 with a remaining 0.0.
