We divide 87313937 by 221
We want to divide 87313937 by 221.

Going ahead to step 1:
If we divide 8 by 221, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 221

Step 2:
The number 221 fits into 87 0 times, leaving a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Include the next digit (3) from the dividend after 87, then repeat: 873 / 221

Advancing to step 3:
221 goes into 873 3 times with a remainder of 210.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 663 from 873 and we're left with 210.
Bring next digit (1) of the dividend behind the 210 and repeat the process: 2101 / 221

Let's proceed to step 4:
The number 221 fits into 2101 9 times, leaving a remainder of 112.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 1989 away from 2101, we end up with 112.
Bring next digit (3) of the dividend behind the 112 and repeat the process: 1123 / 221

Moving on to step 5:
1123 divided by 221 is 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 395.0
Subtract 1105 from 1123 to get 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 221

Step 6:
221 can be fit into 189 0 times, resulting in a remainder of 189.
Put 0 as the next digit of the answer. 
Result so far: 3950.0
If we take 0 away from 189, we end up with 189.
Grab the next digit (3) from the dividend, add it to 189, then carry on: 1893 / 221

Advancing to step 7:
If we divide 1893 by 221, we get 8 and a remainder of 125.
Record the quotient 8 as the next digit in the result. 
Result so far: 39508.0
If we take 1768 away from 1893, we end up with 125.
Grab the next digit (7) from the dividend, add it to 125, then carry on: 1257 / 221

Going ahead to step 8:
When dividing 1257 by 221, we get 5 with a remainder of 152.
Record the quotient 5 as the next digit in the result. 
Result so far: 395085.0
Subtract 1105 from 1257 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 9:
When dividing 1520 by 221, we get 6 with a remainder of 194.
The next digit of our result is 6. 
Result so far: 395085.6
Subtracting 1326 from 1520 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 10:
The number 221 fits into 1940 8 times, leaving a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 395085.68
The remainder is 172 after subtracting 1768 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 11:
1720 divided by 221 is 7 with a remainder of 173.
Put 7 as the next digit of the answer. 
Result so far: 395085.687
Subtract 1547 from 1720 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 12:
When dividing 1730 by 221, we get 7 with a remainder of 183.
Use 7 as the next digit of our solution. 
Result so far: 395085.6877
The remainder is 183 after subtracting 1547 from 1730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Our division results in 395085.6877 with a remaining 0.00183.
