We divide 91206903 by 679
The aim is to understand the frequency of 679 in 91206903.

Going ahead to step 1:
9 divided by 679 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 679

On to step 2:
679 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Grab the next digit (2) from the dividend, add it to 91, then carry on: 912 / 679

Let's proceed to step 3:
When dividing 912 by 679, we get 1 with a remainder of 233.
The next digit of our result is 1. 
Result so far: 1.0
If we take 679 away from 912, we end up with 233.
Take the next digit (0) from the dividend and append it to 233, then repeat: 2330 / 679

Moving on to step 4:
2330 divided by 679 is 3 with a remainder of 293.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 2037 from 2330 leaves us with 293.
Include the next digit (6) from the dividend after 293, then repeat: 2936 / 679

Advancing to step 5:
When dividing 2936 by 679, we get 4 with a remainder of 220.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Subtracting 2716 from 2936 leaves us with 220.
Grab the next digit (9) from the dividend, add it to 220, then carry on: 2209 / 679

Moving on to step 6:
When dividing 2209 by 679, we get 3 with a remainder of 172.
Use 3 as the next digit of our solution. 
Result so far: 1343.0
If we subtract 2037 from 2209, we get 172.
Bring next digit (0) of the dividend behind the 172 and repeat the process: 1720 / 679

Step 7:
1720 divided by 679 is 2 with a remainder of 362.
The next digit of our result is 2. 
Result so far: 13432.0
If we take 1358 away from 1720, we end up with 362.
Fetch the next digit (3) from the dividend, attach it to 362 and continue: 3623 / 679

Let's proceed to step 8:
If we divide 3623 by 679, we get 5 and a remainder of 228.
Put 5 as the next digit of the answer. 
Result so far: 134325.0
Subtract 3395 from 3623 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 9:
679 goes into 2280 3 times with a remainder of 243.
The number 3 becomes the next digit in our result. 
Result so far: 134325.3
Deduct 2037 from 2280 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 10:
When dividing 2430 by 679, we get 3 with a remainder of 393.
Use 3 as the next digit of our solution. 
Result so far: 134325.33
If we take 2037 away from 2430, we end up with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

In conclusion, the division gives 134325.33 with a balance of 0.393.
