We look at the division of 80159480 by 221 
We want to figure out the number of times 80159480 can be divided by 221.

Advancing to step 1:
8 divided by 221 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 221

On to step 2:
221 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 221

Moving on to step 3:
The number 221 fits into 801 3 times, leaving a remainder of 138.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 663 from 801 and we're left with 138.
Bring next digit (5) of the dividend behind the 138 and repeat the process: 1385 / 221

Step 4:
221 can be fit into 1385 6 times, resulting in a remainder of 59.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
If we subtract 1326 from 1385, we get 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 221

Let's proceed to step 5:
221 can be fit into 599 2 times, resulting in a remainder of 157.
Record the quotient 2 as the next digit in the result. 
Result so far: 362.0
The remainder is 157 after subtracting 442 from 599.
Include the next digit (4) from the dividend after 157, then repeat: 1574 / 221

On to step 6:
221 goes into 1574 7 times with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 3627.0
If we take 1547 away from 1574, we end up with 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 221

Advancing to step 7:
If we divide 278 by 221, we get 1 and a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 36271.0
Deduct 221 from 278 and we're left with 57.
Bring next digit (0) of the dividend behind the 57 and repeat the process: 570 / 221

Let's proceed to step 8:
The number 221 fits into 570 2 times, leaving a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 362712.0
The remainder is 128 after subtracting 442 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 9:
If we divide 1280 by 221, we get 5 and a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 362712.5
If we subtract 1105 from 1280, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 10:
If we divide 1750 by 221, we get 7 and a remainder of 203.
The next digit of our result is 7. 
Result so far: 362712.57
Subtract 1547 from 1750 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

On to step 11:
221 goes into 2030 9 times with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 362712.579
If we take 1989 away from 2030, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 12:
221 goes into 410 1 times with a remainder of 189.
The next digit of our result is 1. 
Result so far: 362712.5791
If we take 221 away from 410, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 13:
1890 divided by 221 is 8 with a remainder of 122.
The next digit of our result is 8. 
Result so far: 362712.57918
If we subtract 1768 from 1890, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 14:
221 goes into 1220 5 times with a remainder of 115.
The number 5 becomes the next digit in our result. 
Result so far: 362712.579185
If we take 1105 away from 1220, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 15:
221 goes into 1150 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 362712.5791855
The remainder is 45 after subtracting 1105 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 362712.5791855 with a remaining 4.5e-07.
