641078 divided by 66 
Let's see how many times 66 fits into 641078.

Step 1:
The number 66 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 66

Moving on to step 2:
When dividing 64 by 66, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 66

On to step 3:
66 can be fit into 641 9 times, resulting in a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 594 away from 641, we end up with 47.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 66

Let's proceed to step 4:
If we divide 470 by 66, we get 7 and a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we subtract 462 from 470, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 66

Going ahead to step 5:
If we divide 87 by 66, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 971.0
Deduct 66 from 87 and we're left with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 66

Going ahead to step 6:
The number 66 fits into 218 3 times, leaving a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 9713.0
Subtract 198 from 218 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
If we divide 200 by 66, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 9713.3
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
66 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9713.3
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
66 goes into 200 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 9713.303
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
If we divide 20 by 66, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9713.303
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
The number 66 fits into 200 3 times, leaving a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 9713.30303
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9713.30303
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
66 can be fit into 200 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 9713.3030303
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
If we divide 20 by 66, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9713.3030303
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 9713.3030303, with a leftover of 2e-08.
