We look at the division of 9121343 by 746 
The aim is to understand the frequency of 746 in 9121343.

Going ahead to step 1:
746 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 746

On to step 2:
746 can be fit into 91 0 times, resulting in a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Take the next digit (2) from the dividend and append it to 91, then repeat: 912 / 746

On to step 3:
If we divide 912 by 746, we get 1 and a remainder of 166.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 746 from 912 to get 166.
Fetch the next digit (1) from the dividend, attach it to 166 and continue: 1661 / 746

Advancing to step 4:
If we divide 1661 by 746, we get 2 and a remainder of 169.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1492 away from 1661, we end up with 169.
Grab the next digit (3) from the dividend, add it to 169, then carry on: 1693 / 746

Step 5:
The number 746 fits into 1693 2 times, leaving a remainder of 201.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
The remainder is 201 after subtracting 1492 from 1693.
Bring next digit (4) of the dividend behind the 201 and repeat the process: 2014 / 746

On to step 6:
2014 divided by 746 is 2 with a remainder of 522.
Record the quotient 2 as the next digit in the result. 
Result so far: 1222.0
The remainder is 522 after subtracting 1492 from 2014.
Take the next digit (3) from the dividend and append it to 522, then repeat: 5223 / 746

Let's proceed to step 7:
When dividing 5223 by 746, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 12227.0
Subtract 5222 from 5223 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
The number 746 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12227.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
746 goes into 100 0 times with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 12227.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 12227.0 with a remaining 0.1.
