We look at the division of 75925789 by 993 
The aim is to understand the frequency of 993 in 75925789.

Moving on to step 1:
993 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 993

On to step 2:
993 can be fit into 75 0 times, resulting in a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Bring next digit (9) of the dividend behind the 75 and repeat the process: 759 / 993

Let's proceed to step 3:
If we divide 759 by 993, we get 0 and a remainder of 759.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 759 leaves us with 759.
Append the next digit (2) from the dividend to 759 and continue with: 7592 / 993

Step 4:
7592 divided by 993 is 7 with a remainder of 641.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 6951 from 7592, we get 641.
Fetch the next digit (5) from the dividend, attach it to 641 and continue: 6415 / 993

Step 5:
6415 divided by 993 is 6 with a remainder of 457.
Write down 6 as next digit of the result. 
Result so far: 76.0
If we take 5958 away from 6415, we end up with 457.
Include the next digit (7) from the dividend after 457, then repeat: 4577 / 993

Moving on to step 6:
If we divide 4577 by 993, we get 4 and a remainder of 605.
Use 4 as the next digit of our solution. 
Result so far: 764.0
Subtracting 3972 from 4577 leaves us with 605.
Fetch the next digit (8) from the dividend, attach it to 605 and continue: 6058 / 993

Going ahead to step 7:
The number 993 fits into 6058 6 times, leaving a remainder of 100.
The next digit of our result is 6. 
Result so far: 7646.0
If we subtract 5958 from 6058, we get 100.
Append the next digit (9) from the dividend to 100 and continue with: 1009 / 993

Advancing to step 8:
993 goes into 1009 1 times with a remainder of 16.
The next digit of our result is 1. 
Result so far: 76461.0
Subtracting 993 from 1009 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
The number 993 fits into 160 0 times, leaving a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 76461.0
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
The number 993 fits into 1600 1 times, leaving a remainder of 607.
Write down 1 as next digit of the result. 
Result so far: 76461.01
If we subtract 993 from 1600, we get 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Going ahead to step 11:
If we divide 6070 by 993, we get 6 and a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 76461.016
Deduct 5958 from 6070 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
If we divide 1120 by 993, we get 1 and a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 76461.0161
The remainder is 127 after subtracting 993 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 13:
1270 divided by 993 is 1 with a remainder of 277.
Record the quotient 1 as the next digit in the result. 
Result so far: 76461.01611
If we take 993 away from 1270, we end up with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

The final outcome is 76461.01611, with a leftover of 0.000277.
