We look at the division of 75370146 by 997 
The aim is to understand the frequency of 997 in 75370146.

Let's proceed to step 1:
997 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 997

Going ahead to step 2:
997 goes into 75 0 times with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 997

Going ahead to step 3:
753 divided by 997 is 0 with a remainder of 753.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 753 and we're left with 753.
Take the next digit (7) from the dividend and append it to 753, then repeat: 7537 / 997

On to step 4:
997 goes into 7537 7 times with a remainder of 558.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 6979 from 7537 leaves us with 558.
Bring next digit (0) of the dividend behind the 558 and repeat the process: 5580 / 997

Step 5:
When dividing 5580 by 997, we get 5 with a remainder of 595.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtracting 4985 from 5580 leaves us with 595.
Grab the next digit (1) from the dividend, add it to 595, then carry on: 5951 / 997

Moving on to step 6:
When dividing 5951 by 997, we get 5 with a remainder of 966.
Record the quotient 5 as the next digit in the result. 
Result so far: 755.0
If we subtract 4985 from 5951, we get 966.
Take the next digit (4) from the dividend and append it to 966, then repeat: 9664 / 997

Moving on to step 7:
997 can be fit into 9664 9 times, resulting in a remainder of 691.
Record the quotient 9 as the next digit in the result. 
Result so far: 7559.0
Subtract 8973 from 9664 to get 691.
Grab the next digit (6) from the dividend, add it to 691, then carry on: 6916 / 997

Moving on to step 8:
If we divide 6916 by 997, we get 6 and a remainder of 934.
Record the quotient 6 as the next digit in the result. 
Result so far: 75596.0
Subtract 5982 from 6916 to get 934.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9340, and continue the process.

Going ahead to step 9:
997 goes into 9340 9 times with a remainder of 367.
Record the quotient 9 as the next digit in the result. 
Result so far: 75596.9
Subtract 8973 from 9340 to get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Going ahead to step 10:
The number 997 fits into 3670 3 times, leaving a remainder of 679.
Record the quotient 3 as the next digit in the result. 
Result so far: 75596.93
If we subtract 2991 from 3670, we get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Step 11:
The number 997 fits into 6790 6 times, leaving a remainder of 808.
Record the quotient 6 as the next digit in the result. 
Result so far: 75596.936
If we subtract 5982 from 6790, we get 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Going ahead to step 12:
If we divide 8080 by 997, we get 8 and a remainder of 104.
The next digit of our result is 8. 
Result so far: 75596.9368
If we subtract 7976 from 8080, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 13:
997 can be fit into 1040 1 times, resulting in a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 75596.93681
If we subtract 997 from 1040, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 14:
When dividing 430 by 997, we get 0 with a remainder of 430.
The next digit of our result is 0. 
Result so far: 75596.93681
Deduct 0 from 430 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 15:
997 can be fit into 4300 4 times, resulting in a remainder of 312.
Use 4 as the next digit of our solution. 
Result so far: 75596.9368104
Subtracting 3988 from 4300 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 16:
The number 997 fits into 3120 3 times, leaving a remainder of 129.
Record the quotient 3 as the next digit in the result. 
Result so far: 75596.93681043
Subtract 2991 from 3120 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The final outcome is 75596.93681043, with a leftover of 1.29e-07.
