79448959 divided by 221 
We want to divide 79448959 by 221.

Let's proceed to step 1:
The number 221 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 221

Advancing to step 2:
The number 221 fits into 79 0 times, leaving a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Grab the next digit (4) from the dividend, add it to 79, then carry on: 794 / 221

Step 3:
221 goes into 794 3 times with a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 663 from 794, we get 131.
Append the next digit (4) from the dividend to 131 and continue with: 1314 / 221

Going ahead to step 4:
If we divide 1314 by 221, we get 5 and a remainder of 209.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Deduct 1105 from 1314 and we're left with 209.
Grab the next digit (8) from the dividend, add it to 209, then carry on: 2098 / 221

Step 5:
The number 221 fits into 2098 9 times, leaving a remainder of 109.
The number 9 becomes the next digit in our result. 
Result so far: 359.0
If we take 1989 away from 2098, we end up with 109.
Grab the next digit (9) from the dividend, add it to 109, then carry on: 1099 / 221

Step 6:
When dividing 1099 by 221, we get 4 with a remainder of 215.
Write down 4 as next digit of the result. 
Result so far: 3594.0
Subtracting 884 from 1099 leaves us with 215.
Bring next digit (5) of the dividend behind the 215 and repeat the process: 2155 / 221

Advancing to step 7:
221 goes into 2155 9 times with a remainder of 166.
Use 9 as the next digit of our solution. 
Result so far: 35949.0
Deduct 1989 from 2155 and we're left with 166.
Grab the next digit (9) from the dividend, add it to 166, then carry on: 1669 / 221

Moving on to step 8:
221 can be fit into 1669 7 times, resulting in a remainder of 122.
The number 7 becomes the next digit in our result. 
Result so far: 359497.0
If we subtract 1547 from 1669, 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.

Going ahead to step 9:
If we divide 1220 by 221, we get 5 and a remainder of 115.
The next digit of our result is 5. 
Result so far: 359497.5
If we subtract 1105 from 1220, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 10:
221 goes into 1150 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 359497.55
If we subtract 1105 from 1150, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 359497.55 with a remainder of 0.045.
