Let's divide 661917 by 99
We want to divide 661917 by 99.

Going ahead to step 1:
If we divide 6 by 99, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 99

Let's proceed to step 2:
The number 99 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 99

Going ahead to step 3:
The number 99 fits into 661 6 times, leaving a remainder of 67.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 594 from 661 leaves us with 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 99

On to step 4:
The number 99 fits into 679 6 times, leaving a remainder of 85.
Write down 6 as next digit of the result. 
Result so far: 66.0
Subtracting 594 from 679 leaves us with 85.
Fetch the next digit (1) from the dividend, attach it to 85 and continue: 851 / 99

On to step 5:
When dividing 851 by 99, we get 8 with a remainder of 59.
The number 8 becomes the next digit in our result. 
Result so far: 668.0
Deduct 792 from 851 and we're left with 59.
Grab the next digit (7) from the dividend, add it to 59, then carry on: 597 / 99

Advancing to step 6:
When dividing 597 by 99, we get 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6686.0
If we take 594 away from 597, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 99 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 6686.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 99, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 6686.03
Deduct 297 from 300 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
99 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 6686.03
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
If we divide 300 by 99, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 6686.0303
Subtract 297 from 300 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
99 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 6686.0303
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
99 can be fit into 300 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 6686.030303
If we subtract 297 from 300, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
If we divide 30 by 99, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 6686.030303
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
99 goes into 300 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 6686.03030303
Subtracting 297 from 300 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 6686.03030303, and the remainder is 3e-09.
