15209005 ÷ 220 
We're looking to find how many times 220 goes into 15209005.

Advancing to step 1:
If we divide 1 by 220, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 220

Advancing to step 2:
220 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 220

Advancing to step 3:
152 divided by 220 is 0 with a remainder of 152.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 152 leaves us with 152.
Take the next digit (0) from the dividend and append it to 152, then repeat: 1520 / 220

On to step 4:
1520 divided by 220 is 6 with a remainder of 200.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 1320 from 1520 to get 200.
Bring next digit (9) of the dividend behind the 200 and repeat the process: 2009 / 220

Going ahead to step 5:
The number 220 fits into 2009 9 times, leaving a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we take 1980 away from 2009, we end up with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 220

Step 6:
220 goes into 290 1 times with a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 691.0
If we take 220 away from 290, we end up with 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 220

Let's proceed to step 7:
The number 220 fits into 700 3 times, leaving a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 6913.0
The remainder is 40 after subtracting 660 from 700.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 220

Advancing to step 8:
The number 220 fits into 405 1 times, leaving a remainder of 185.
Use 1 as the next digit of our solution. 
Result so far: 69131.0
The remainder is 185 after subtracting 220 from 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 9:
220 can be fit into 1850 8 times, resulting in a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 69131.8
Deduct 1760 from 1850 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
220 can be fit into 900 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 69131.84
If we subtract 880 from 900, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
If we divide 200 by 220, we get 0 and a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 69131.84
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
If we divide 2000 by 220, we get 9 and a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 69131.8409
If we take 1980 away from 2000, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
When dividing 200 by 220, we get 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 69131.8409
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 14:
If we divide 2000 by 220, we get 9 and a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 69131.840909
Subtract 1980 from 2000 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 15:
220 can be fit into 200 0 times, resulting in a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 69131.840909
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 16:
When dividing 2000 by 220, we get 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 69131.84090909
If we subtract 1980 from 2000, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 69131.84090909, with a leftover of 2e-08.
