Let's divide 66522454 by 997
The aim is to understand the frequency of 997 in 66522454.

Going ahead to step 1:
997 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
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 / 997

Step 2:
997 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 997

Advancing to step 3:
997 can be fit into 665 0 times, resulting in a remainder of 665.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 665, we end up with 665.
Append the next digit (2) from the dividend to 665 and continue with: 6652 / 997

Advancing to step 4:
The number 997 fits into 6652 6 times, leaving a remainder of 670.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 5982 from 6652 and we're left with 670.
Take the next digit (2) from the dividend and append it to 670, then repeat: 6702 / 997

Step 5:
997 can be fit into 6702 6 times, resulting in a remainder of 720.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtracting 5982 from 6702 leaves us with 720.
Fetch the next digit (4) from the dividend, attach it to 720 and continue: 7204 / 997

Step 6:
If we divide 7204 by 997, we get 7 and a remainder of 225.
Use 7 as the next digit of our solution. 
Result so far: 667.0
Deduct 6979 from 7204 and we're left with 225.
Grab the next digit (5) from the dividend, add it to 225, then carry on: 2255 / 997

On to step 7:
997 can be fit into 2255 2 times, resulting in a remainder of 261.
The next digit of our result is 2. 
Result so far: 6672.0
Subtract 1994 from 2255 to get 261.
Take the next digit (4) from the dividend and append it to 261, then repeat: 2614 / 997

Going ahead to step 8:
997 can be fit into 2614 2 times, resulting in a remainder of 620.
Put 2 as the next digit of the answer. 
Result so far: 66722.0
If we take 1994 away from 2614, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 9:
997 can be fit into 6200 6 times, resulting in a remainder of 218.
Put 6 as the next digit of the answer. 
Result so far: 66722.6
Subtracting 5982 from 6200 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 10:
When dividing 2180 by 997, we get 2 with a remainder of 186.
The next digit of our result is 2. 
Result so far: 66722.62
Deduct 1994 from 2180 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 11:
997 goes into 1860 1 times with a remainder of 863.
Put 1 as the next digit of the answer. 
Result so far: 66722.621
Subtract 997 from 1860 to get 863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

Step 12:
8630 divided by 997 is 8 with a remainder of 654.
Write down 8 as next digit of the result. 
Result so far: 66722.6218
If we subtract 7976 from 8630, we get 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Going ahead to step 13:
If we divide 6540 by 997, we get 6 and a remainder of 558.
Put 6 as the next digit of the answer. 
Result so far: 66722.62186
Deduct 5982 from 6540 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 14:
When dividing 5580 by 997, we get 5 with a remainder of 595.
The next digit of our result is 5. 
Result so far: 66722.621865
The remainder is 595 after subtracting 4985 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Step 15:
If we divide 5950 by 997, we get 5 and a remainder of 965.
Put 5 as the next digit of the answer. 
Result so far: 66722.6218655
If we take 4985 away from 5950, we end up with 965.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9650, and continue the process.

After the division, we end up with 66722.6218655 and a remainder of 9.65e-06.
