We're dividing 23157780 by 221 
Let's see how many times 221 fits into 23157780.

Going ahead to step 1:
221 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 221

Let's proceed to step 2:
221 goes into 23 0 times with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 221

Step 3:
231 divided by 221 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 221 from 231, we get 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 221

Advancing to step 4:
If we divide 105 by 221, we get 0 and a remainder of 105.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 105, we end up with 105.
Append the next digit (7) from the dividend to 105 and continue with: 1057 / 221

On to step 5:
221 can be fit into 1057 4 times, resulting in a remainder of 173.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Subtract 884 from 1057 to get 173.
Include the next digit (7) from the dividend after 173, then repeat: 1737 / 221

Moving on to step 6:
The number 221 fits into 1737 7 times, leaving a remainder of 190.
The number 7 becomes the next digit in our result. 
Result so far: 1047.0
The remainder is 190 after subtracting 1547 from 1737.
Take the next digit (8) from the dividend and append it to 190, then repeat: 1908 / 221

Moving on to step 7:
The number 221 fits into 1908 8 times, leaving a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 10478.0
Subtracting 1768 from 1908 leaves us with 140.
Grab the next digit (0) from the dividend, add it to 140, then carry on: 1400 / 221

Moving on to step 8:
1400 divided by 221 is 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 104786.0
The remainder is 74 after subtracting 1326 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 9:
If we divide 740 by 221, we get 3 and a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 104786.3
Subtracting 663 from 740 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 10:
The number 221 fits into 770 3 times, leaving a remainder of 107.
Put 3 as the next digit of the answer. 
Result so far: 104786.33
If we subtract 663 from 770, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Our division results in 104786.33 with a remaining 0.107.
