79409067 ÷ 220 
Our goal is to divide 79409067 by 220.

Advancing to step 1:
The number 220 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 220

Moving on to step 2:
220 goes into 79 0 times with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Include the next digit (4) from the dividend after 79, then repeat: 794 / 220

On to step 3:
The number 220 fits into 794 3 times, leaving a remainder of 134.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 660 from 794 leaves us with 134.
Bring next digit (0) of the dividend behind the 134 and repeat the process: 1340 / 220

On to step 4:
When dividing 1340 by 220, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we subtract 1320 from 1340, we get 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 220

Let's proceed to step 5:
220 goes into 209 0 times with a remainder of 209.
The number 0 becomes the next digit in our result. 
Result so far: 360.0
The remainder is 209 after subtracting 0 from 209.
Append the next digit (0) from the dividend to 209 and continue with: 2090 / 220

Going ahead to step 6:
2090 divided by 220 is 9 with a remainder of 110.
Use 9 as the next digit of our solution. 
Result so far: 3609.0
Deduct 1980 from 2090 and we're left with 110.
Fetch the next digit (6) from the dividend, attach it to 110 and continue: 1106 / 220

Let's proceed to step 7:
220 goes into 1106 5 times with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 36095.0
Subtract 1100 from 1106 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 220

Moving on to step 8:
220 goes into 67 0 times with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 360950.0
If we take 0 away from 67, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 9:
220 goes into 670 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 360950.3
If we subtract 660 from 670, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
If we divide 100 by 220, we get 0 and a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 360950.3
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
If we divide 1000 by 220, we get 4 and a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 360950.304
The remainder is 120 after subtracting 880 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
When dividing 1200 by 220, we get 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 360950.3045
The remainder is 100 after subtracting 1100 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
The number 220 fits into 1000 4 times, leaving a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 360950.30454
If we take 880 away from 1000, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 14:
If we divide 1200 by 220, we get 5 and a remainder of 100.
The next digit of our result is 5. 
Result so far: 360950.304545
Deduct 1100 from 1200 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 15:
When dividing 1000 by 220, we get 4 with a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 360950.3045454
The remainder is 120 after subtracting 880 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 16:
The number 220 fits into 1200 5 times, leaving a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 360950.30454545
Subtracting 1100 from 1200 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 360950.30454545, with a leftover of 1e-07.
