64031670 ÷ 66 
Let's see how many times 66 fits into 64031670.

On to step 1:
66 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 66

Advancing to step 2:
64 divided by 66 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 66

Moving on to step 3:
When dividing 640 by 66, we get 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 46 after subtracting 594 from 640.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 66

Moving on to step 4:
66 goes into 463 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we take 462 away from 463, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 66

Advancing to step 5:
11 divided by 66 is 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 970.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 66

On to step 6:
66 goes into 116 1 times with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 9701.0
If we take 66 away from 116, we end up with 50.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 66

Let's proceed to step 7:
If we divide 507 by 66, we get 7 and a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 97017.0
Deduct 462 from 507 and we're left with 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 66

Step 8:
66 goes into 450 6 times with a remainder of 54.
The next digit of our result is 6. 
Result so far: 970176.0
If we take 396 away from 450, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
66 goes into 540 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 970176.8
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
66 can be fit into 120 1 times, resulting in a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 970176.81
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
66 goes into 540 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 970176.818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
66 goes into 120 1 times with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 970176.8181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 13:
When dividing 540 by 66, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 970176.81818
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 970176.818181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 15:
66 can be fit into 540 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 970176.8181818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 16:
66 goes into 120 1 times with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 970176.81818181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 970176.81818181, and the remainder is 5.4e-08.
