We look at the division of 68486630 by 997 
The aim is to understand the frequency of 997 in 68486630.

Let's proceed to step 1:
6 divided by 997 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 997

Going ahead to step 2:
997 can be fit into 68 0 times, resulting in a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 997

Step 3:
When dividing 684 by 997, we get 0 with a remainder of 684.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 684, we end up with 684.
Take the next digit (8) from the dividend and append it to 684, then repeat: 6848 / 997

Moving on to step 4:
If we divide 6848 by 997, we get 6 and a remainder of 866.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 5982 from 6848 to get 866.
Take the next digit (6) from the dividend and append it to 866, then repeat: 8666 / 997

Let's proceed to step 5:
If we divide 8666 by 997, we get 8 and a remainder of 690.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Deduct 7976 from 8666 and we're left with 690.
Take the next digit (6) from the dividend and append it to 690, then repeat: 6906 / 997

Moving on to step 6:
If we divide 6906 by 997, we get 6 and a remainder of 924.
The next digit of our result is 6. 
Result so far: 686.0
If we subtract 5982 from 6906, we get 924.
Take the next digit (3) from the dividend and append it to 924, then repeat: 9243 / 997

Step 7:
997 goes into 9243 9 times with a remainder of 270.
Record the quotient 9 as the next digit in the result. 
Result so far: 6869.0
If we subtract 8973 from 9243, we get 270.
Fetch the next digit (0) from the dividend, attach it to 270 and continue: 2700 / 997

Going ahead to step 8:
If we divide 2700 by 997, we get 2 and a remainder of 706.
The number 2 becomes the next digit in our result. 
Result so far: 68692.0
Subtract 1994 from 2700 to get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Going ahead to step 9:
The number 997 fits into 7060 7 times, leaving a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 68692.7
If we take 6979 away from 7060, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 10:
810 divided by 997 is 0 with a remainder of 810.
Write down 0 as next digit of the result. 
Result so far: 68692.7
The remainder is 810 after subtracting 0 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Moving on to step 11:
When dividing 8100 by 997, we get 8 with a remainder of 124.
The next digit of our result is 8. 
Result so far: 68692.708
Subtract 7976 from 8100 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 12:
997 can be fit into 1240 1 times, resulting in a remainder of 243.
Record the quotient 1 as the next digit in the result. 
Result so far: 68692.7081
Subtract 997 from 1240 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 13:
If we divide 2430 by 997, we get 2 and a remainder of 436.
The next digit of our result is 2. 
Result so far: 68692.70812
Subtracting 1994 from 2430 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 14:
If we divide 4360 by 997, we get 4 and a remainder of 372.
Put 4 as the next digit of the answer. 
Result so far: 68692.708124
The remainder is 372 after subtracting 3988 from 4360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 15:
If we divide 3720 by 997, we get 3 and a remainder of 729.
Use 3 as the next digit of our solution. 
Result so far: 68692.7081243
Subtracting 2991 from 3720 leaves us with 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

On to step 16:
7290 divided by 997 is 7 with a remainder of 311.
The next digit of our result is 7. 
Result so far: 68692.70812437
If we take 6979 away from 7290, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

The quotient of the division is 68692.70812437, and the remainder is 3.11e-07.
