We look at the division of 66649147 by 661 
Let's see how many times 661 fits into 66649147.

Let's proceed to step 1:
If we divide 6 by 661, 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.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 661

On to step 2:
The number 661 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 661

On to step 3:
When dividing 666 by 661, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 5 after subtracting 661 from 666.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 661

Advancing to step 4:
When dividing 54 by 661, we get 0 with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 54 leaves us with 54.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 661

Step 5:
The number 661 fits into 549 0 times, leaving a remainder of 549.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 549 leaves us with 549.
Grab the next digit (1) from the dividend, add it to 549, then carry on: 5491 / 661

Going ahead to step 6:
When dividing 5491 by 661, we get 8 with a remainder of 203.
Record the quotient 8 as the next digit in the result. 
Result so far: 1008.0
If we subtract 5288 from 5491, we get 203.
Take the next digit (4) from the dividend and append it to 203, then repeat: 2034 / 661

Let's proceed to step 7:
When dividing 2034 by 661, we get 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 10083.0
If we subtract 1983 from 2034, we get 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 661

On to step 8:
If we divide 517 by 661, we get 0 and a remainder of 517.
Record the quotient 0 as the next digit in the result. 
Result so far: 100830.0
Deduct 0 from 517 and we're left with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

On to step 9:
When dividing 5170 by 661, we get 7 with a remainder of 543.
The next digit of our result is 7. 
Result so far: 100830.7
Deduct 4627 from 5170 and we're left with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

On to step 10:
The number 661 fits into 5430 8 times, leaving a remainder of 142.
The next digit of our result is 8. 
Result so far: 100830.78
If we take 5288 away from 5430, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 11:
661 can be fit into 1420 2 times, resulting in a remainder of 98.
The next digit of our result is 2. 
Result so far: 100830.782
Deduct 1322 from 1420 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 12:
If we divide 980 by 661, we get 1 and a remainder of 319.
Put 1 as the next digit of the answer. 
Result so far: 100830.7821
If we subtract 661 from 980, we get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Step 13:
661 goes into 3190 4 times with a remainder of 546.
Write down 4 as next digit of the result. 
Result so far: 100830.78214
The remainder is 546 after subtracting 2644 from 3190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

On to step 14:
5460 divided by 661 is 8 with a remainder of 172.
Put 8 as the next digit of the answer. 
Result so far: 100830.782148
If we take 5288 away from 5460, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 15:
The number 661 fits into 1720 2 times, leaving a remainder of 398.
The number 2 becomes the next digit in our result. 
Result so far: 100830.7821482
If we subtract 1322 from 1720, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 16:
The number 661 fits into 3980 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 100830.78214826
The remainder is 14 after subtracting 3966 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 100830.78214826 and a remainder of 1.4e-08.
