We look at the division of 61661781 by 931 
The aim is to understand the frequency of 931 in 61661781.

Moving on to step 1:
931 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 931

Advancing to step 2:
If we divide 61 by 931, we get 0 and a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Include the next digit (6) from the dividend after 61, then repeat: 616 / 931

Advancing to step 3:
When dividing 616 by 931, we get 0 with a remainder of 616.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 616 after subtracting 0 from 616.
Fetch the next digit (6) from the dividend, attach it to 616 and continue: 6166 / 931

Advancing to step 4:
If we divide 6166 by 931, we get 6 and a remainder of 580.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 5586 from 6166 to get 580.
Append the next digit (1) from the dividend to 580 and continue with: 5801 / 931

Moving on to step 5:
931 goes into 5801 6 times with a remainder of 215.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Deduct 5586 from 5801 and we're left with 215.
Bring next digit (7) of the dividend behind the 215 and repeat the process: 2157 / 931

Going ahead to step 6:
If we divide 2157 by 931, we get 2 and a remainder of 295.
The number 2 becomes the next digit in our result. 
Result so far: 662.0
If we subtract 1862 from 2157, we get 295.
Include the next digit (8) from the dividend after 295, then repeat: 2958 / 931

On to step 7:
931 can be fit into 2958 3 times, resulting in a remainder of 165.
The next digit of our result is 3. 
Result so far: 6623.0
If we subtract 2793 from 2958, we get 165.
Fetch the next digit (1) from the dividend, attach it to 165 and continue: 1651 / 931

Let's proceed to step 8:
931 goes into 1651 1 times with a remainder of 720.
Record the quotient 1 as the next digit in the result. 
Result so far: 66231.0
Subtracting 931 from 1651 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 9:
If we divide 7200 by 931, we get 7 and a remainder of 683.
The next digit of our result is 7. 
Result so far: 66231.7
Deduct 6517 from 7200 and we're left with 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Advancing to step 10:
931 goes into 6830 7 times with a remainder of 313.
Put 7 as the next digit of the answer. 
Result so far: 66231.77
If we take 6517 away from 6830, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

The final result is 66231.77 with a remainder of 0.313.
