We divide 66788434 by 997
We want to figure out the number of times 66788434 can be divided by 997.

On to step 1:
6 divided by 997 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 997

Let's proceed to step 2:
When dividing 66 by 997, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (7) from the dividend, add it to 66, then carry on: 667 / 997

On to step 3:
If we divide 667 by 997, we get 0 and a remainder of 667.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 667 after subtracting 0 from 667.
Bring next digit (8) of the dividend behind the 667 and repeat the process: 6678 / 997

Let's proceed to step 4:
The number 997 fits into 6678 6 times, leaving a remainder of 696.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 5982 from 6678 leaves us with 696.
Grab the next digit (8) from the dividend, add it to 696, then carry on: 6968 / 997

Going ahead to step 5:
When dividing 6968 by 997, we get 6 with a remainder of 986.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Subtract 5982 from 6968 to get 986.
Append the next digit (4) from the dividend to 986 and continue with: 9864 / 997

Moving on to step 6:
997 goes into 9864 9 times with a remainder of 891.
Record the quotient 9 as the next digit in the result. 
Result so far: 669.0
Subtract 8973 from 9864 to get 891.
Fetch the next digit (3) from the dividend, attach it to 891 and continue: 8913 / 997

Let's proceed to step 7:
When dividing 8913 by 997, we get 8 with a remainder of 937.
Write down 8 as next digit of the result. 
Result so far: 6698.0
If we subtract 7976 from 8913, we get 937.
Append the next digit (4) from the dividend to 937 and continue with: 9374 / 997

Step 8:
When dividing 9374 by 997, we get 9 with a remainder of 401.
The next digit of our result is 9. 
Result so far: 66989.0
If we subtract 8973 from 9374, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Advancing to step 9:
997 can be fit into 4010 4 times, resulting in a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 66989.4
The remainder is 22 after subtracting 3988 from 4010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
If we divide 220 by 997, we get 0 and a remainder of 220.
The next digit of our result is 0. 
Result so far: 66989.4
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 11:
2200 divided by 997 is 2 with a remainder of 206.
Put 2 as the next digit of the answer. 
Result so far: 66989.402
If we subtract 1994 from 2200, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 12:
If we divide 2060 by 997, we get 2 and a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 66989.4022
If we subtract 1994 from 2060, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 66989.4022 with a remaining 0.00066.
