We divide 7866617 by 221
We're looking to find how many times 221 goes into 7866617.

On to step 1:
221 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 221

Going ahead to step 2:
78 divided by 221 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (6) from the dividend to 78 and continue with: 786 / 221

On to step 3:
786 divided by 221 is 3 with a remainder of 123.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 663 from 786 leaves us with 123.
Take the next digit (6) from the dividend and append it to 123, then repeat: 1236 / 221

Moving on to step 4:
1236 divided by 221 is 5 with a remainder of 131.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we subtract 1105 from 1236, we get 131.
Include the next digit (6) from the dividend after 131, then repeat: 1316 / 221

Advancing to step 5:
If we divide 1316 by 221, we get 5 and a remainder of 211.
Record the quotient 5 as the next digit in the result. 
Result so far: 355.0
Subtract 1105 from 1316 to get 211.
Fetch the next digit (1) from the dividend, attach it to 211 and continue: 2111 / 221

Let's proceed to step 6:
221 can be fit into 2111 9 times, resulting in a remainder of 122.
Write down 9 as next digit of the result. 
Result so far: 3559.0
If we subtract 1989 from 2111, we get 122.
Bring next digit (7) of the dividend behind the 122 and repeat the process: 1227 / 221

Going ahead to step 7:
If we divide 1227 by 221, we get 5 and a remainder of 122.
Put 5 as the next digit of the answer. 
Result so far: 35595.0
Subtract 1105 from 1227 to 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.

On to step 8:
1220 divided by 221 is 5 with a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 35595.5
Deduct 1105 from 1220 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 9:
If we divide 1150 by 221, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 35595.55
Subtract 1105 from 1150 to 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 quotient of the division is 35595.55, and the remainder is 0.045.
