28135534 ÷ 221 
We want to divide 28135534 by 221.

Let's proceed to step 1:
221 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 221

Going ahead to step 2:
221 goes into 28 0 times with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 221

On to step 3:
The number 221 fits into 281 1 times, leaving a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 221 from 281, we get 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 221

Let's proceed to step 4:
If we divide 603 by 221, we get 2 and a remainder of 161.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 442 from 603, we get 161.
Include the next digit (5) from the dividend after 161, then repeat: 1615 / 221

Advancing to step 5:
221 goes into 1615 7 times with a remainder of 68.
Write down 7 as next digit of the result. 
Result so far: 127.0
If we subtract 1547 from 1615, we get 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 221

Step 6:
The number 221 fits into 685 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 1273.0
If we subtract 663 from 685, we get 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 221

Moving on to step 7:
The number 221 fits into 223 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 12731.0
The remainder is 2 after subtracting 221 from 223.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 221

Step 8:
24 divided by 221 is 0 with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 127310.0
Deduct 0 from 24 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
The number 221 fits into 240 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 127310.1
Deduct 221 from 240 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
221 goes into 190 0 times with a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 127310.1
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 11:
The number 221 fits into 1900 8 times, leaving a remainder of 132.
The number 8 becomes the next digit in our result. 
Result so far: 127310.108
The remainder is 132 after subtracting 1768 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 12:
The number 221 fits into 1320 5 times, leaving a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 127310.1085
Subtract 1105 from 1320 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 13:
If we divide 2150 by 221, we get 9 and a remainder of 161.
The next digit of our result is 9. 
Result so far: 127310.10859
Subtracting 1989 from 2150 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Advancing to step 14:
If we divide 1610 by 221, we get 7 and a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 127310.108597
Subtract 1547 from 1610 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 15:
If we divide 630 by 221, we get 2 and a remainder of 188.
Put 2 as the next digit of the answer. 
Result so far: 127310.1085972
If we take 442 away from 630, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 16:
If we divide 1880 by 221, we get 8 and a remainder of 112.
The next digit of our result is 8. 
Result so far: 127310.10859728
The remainder is 112 after subtracting 1768 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final outcome is 127310.10859728, with a leftover of 1.12e-07.
