We divide 91661409 by 751
The aim is to understand the frequency of 751 in 91661409.

Going ahead to step 1:
751 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 751

Let's proceed to step 2:
When dividing 91 by 751, we get 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (6) from the dividend and append it to 91, then repeat: 916 / 751

Advancing to step 3:
The number 751 fits into 916 1 times, leaving a remainder of 165.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 751 from 916 to get 165.
Append the next digit (6) from the dividend to 165 and continue with: 1656 / 751

On to step 4:
The number 751 fits into 1656 2 times, leaving a remainder of 154.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1502 away from 1656, we end up with 154.
Include the next digit (1) from the dividend after 154, then repeat: 1541 / 751

Advancing to step 5:
751 can be fit into 1541 2 times, resulting in a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
The remainder is 39 after subtracting 1502 from 1541.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 751

On to step 6:
If we divide 394 by 751, we get 0 and a remainder of 394.
The number 0 becomes the next digit in our result. 
Result so far: 1220.0
Subtracting 0 from 394 leaves us with 394.
Take the next digit (0) from the dividend and append it to 394, then repeat: 3940 / 751

Going ahead to step 7:
If we divide 3940 by 751, we get 5 and a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 12205.0
Deduct 3755 from 3940 and we're left with 185.
Fetch the next digit (9) from the dividend, attach it to 185 and continue: 1859 / 751

Step 8:
If we divide 1859 by 751, we get 2 and a remainder of 357.
The number 2 becomes the next digit in our result. 
Result so far: 122052.0
Subtract 1502 from 1859 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Going ahead to step 9:
The number 751 fits into 3570 4 times, leaving a remainder of 566.
The next digit of our result is 4. 
Result so far: 122052.4
If we subtract 3004 from 3570, we get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 10:
When dividing 5660 by 751, we get 7 with a remainder of 403.
The next digit of our result is 7. 
Result so far: 122052.47
If we take 5257 away from 5660, we end up with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Let's proceed to step 11:
4030 divided by 751 is 5 with a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 122052.475
Deduct 3755 from 4030 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 12:
The number 751 fits into 2750 3 times, leaving a remainder of 497.
The number 3 becomes the next digit in our result. 
Result so far: 122052.4753
Subtracting 2253 from 2750 leaves us with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Going ahead to step 13:
751 can be fit into 4970 6 times, resulting in a remainder of 464.
The next digit of our result is 6. 
Result so far: 122052.47536
Subtracting 4506 from 4970 leaves us with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 14:
751 goes into 4640 6 times with a remainder of 134.
Record the quotient 6 as the next digit in the result. 
Result so far: 122052.475366
If we take 4506 away from 4640, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The final outcome is 122052.475366, with a leftover of 1.34e-05.
