Let's divide 87771829 by 221
We want to divide 87771829 by 221.

On to step 1:
221 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 221

Moving on to step 2:
When dividing 87 by 221, we get 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Include the next digit (7) from the dividend after 87, then repeat: 877 / 221

Moving on to step 3:
221 can be fit into 877 3 times, resulting in a remainder of 214.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 663 from 877 to get 214.
Bring next digit (7) of the dividend behind the 214 and repeat the process: 2147 / 221

Going ahead to step 4:
221 can be fit into 2147 9 times, resulting in a remainder of 158.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 1989 away from 2147, we end up with 158.
Fetch the next digit (1) from the dividend, attach it to 158 and continue: 1581 / 221

Advancing to step 5:
When dividing 1581 by 221, we get 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 397.0
Subtract 1547 from 1581 to get 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 221

Going ahead to step 6:
The number 221 fits into 348 1 times, leaving a remainder of 127.
Write down 1 as next digit of the result. 
Result so far: 3971.0
If we take 221 away from 348, we end up with 127.
Grab the next digit (2) from the dividend, add it to 127, then carry on: 1272 / 221

Going ahead to step 7:
If we divide 1272 by 221, we get 5 and a remainder of 167.
Put 5 as the next digit of the answer. 
Result so far: 39715.0
The remainder is 167 after subtracting 1105 from 1272.
Append the next digit (9) from the dividend to 167 and continue with: 1679 / 221

Going ahead to step 8:
When dividing 1679 by 221, we get 7 with a remainder of 132.
Record the quotient 7 as the next digit in the result. 
Result so far: 397157.0
If we take 1547 away from 1679, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 9:
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: 397157.5
Subtracting 1105 from 1320 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 10:
221 can be fit into 2150 9 times, resulting in a remainder of 161.
The next digit of our result is 9. 
Result so far: 397157.59
The remainder is 161 after subtracting 1989 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 11:
1610 divided by 221 is 7 with a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 397157.597
If we subtract 1547 from 1610, we 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.

On to step 12:
When dividing 630 by 221, we get 2 with a remainder of 188.
The next digit of our result is 2. 
Result so far: 397157.5972
If we subtract 442 from 630, we get 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 13:
The number 221 fits into 1880 8 times, leaving a remainder of 112.
The next digit of our result is 8. 
Result so far: 397157.59728
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.

Going ahead to step 14:
221 can be fit into 1120 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 397157.597285
Subtract 1105 from 1120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 15:
221 goes into 150 0 times with a remainder of 150.
The next digit of our result is 0. 
Result so far: 397157.597285
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 16:
The number 221 fits into 1500 6 times, leaving a remainder of 174.
Put 6 as the next digit of the answer. 
Result so far: 397157.59728506
Deduct 1326 from 1500 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

After the division, we end up with 397157.59728506 and a remainder of 1.74e-07.
