Let's divide 91654593 by 904
The aim is to understand the frequency of 904 in 91654593.

Advancing to step 1:
If we divide 9 by 904, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 904

On to step 2:
When dividing 91 by 904, we get 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Append the next digit (6) from the dividend to 91 and continue with: 916 / 904

Step 3:
904 can be fit into 916 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 904 away from 916, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 904

Let's proceed to step 4:
If we divide 125 by 904, we get 0 and a remainder of 125.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 125, we get 125.
Grab the next digit (4) from the dividend, add it to 125, then carry on: 1254 / 904

Advancing to step 5:
When dividing 1254 by 904, we get 1 with a remainder of 350.
Use 1 as the next digit of our solution. 
Result so far: 101.0
The remainder is 350 after subtracting 904 from 1254.
Include the next digit (5) from the dividend after 350, then repeat: 3505 / 904

Advancing to step 6:
When dividing 3505 by 904, we get 3 with a remainder of 793.
Write down 3 as next digit of the result. 
Result so far: 1013.0
If we take 2712 away from 3505, we end up with 793.
Append the next digit (9) from the dividend to 793 and continue with: 7939 / 904

Going ahead to step 7:
904 can be fit into 7939 8 times, resulting in a remainder of 707.
Use 8 as the next digit of our solution. 
Result so far: 10138.0
If we subtract 7232 from 7939, we get 707.
Append the next digit (3) from the dividend to 707 and continue with: 7073 / 904

Going ahead to step 8:
7073 divided by 904 is 7 with a remainder of 745.
The number 7 becomes the next digit in our result. 
Result so far: 101387.0
If we subtract 6328 from 7073, we get 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Moving on to step 9:
904 goes into 7450 8 times with a remainder of 218.
Record the quotient 8 as the next digit in the result. 
Result so far: 101387.8
Deduct 7232 from 7450 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 10:
904 can be fit into 2180 2 times, resulting in a remainder of 372.
Put 2 as the next digit of the answer. 
Result so far: 101387.82
Subtracting 1808 from 2180 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 11:
If we divide 3720 by 904, we get 4 and a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 101387.824
If we take 3616 away from 3720, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 12:
1040 divided by 904 is 1 with a remainder of 136.
Put 1 as the next digit of the answer. 
Result so far: 101387.8241
If we subtract 904 from 1040, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 13:
904 goes into 1360 1 times with a remainder of 456.
The number 1 becomes the next digit in our result. 
Result so far: 101387.82411
Subtracting 904 from 1360 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

The final result is 101387.82411 with a remainder of 0.000456.
