We look at the division of 54130391 by 917 
The aim is to understand the frequency of 917 in 54130391.

Going ahead to step 1:
If we divide 5 by 917, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 917

Going ahead to step 2:
54 divided by 917 is 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 917

Moving on to step 3:
The number 917 fits into 541 0 times, leaving a remainder of 541.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 541 and we're left with 541.
Include the next digit (3) from the dividend after 541, then repeat: 5413 / 917

Going ahead to step 4:
5413 divided by 917 is 5 with a remainder of 828.
The next digit of our result is 5. 
Result so far: 5.0
If we take 4585 away from 5413, we end up with 828.
Fetch the next digit (0) from the dividend, attach it to 828 and continue: 8280 / 917

Let's proceed to step 5:
The number 917 fits into 8280 9 times, leaving a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 59.0
If we take 8253 away from 8280, we end up with 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 917

On to step 6:
917 can be fit into 273 0 times, resulting in a remainder of 273.
The number 0 becomes the next digit in our result. 
Result so far: 590.0
If we subtract 0 from 273, we get 273.
Grab the next digit (9) from the dividend, add it to 273, then carry on: 2739 / 917

Step 7:
If we divide 2739 by 917, we get 2 and a remainder of 905.
Write down 2 as next digit of the result. 
Result so far: 5902.0
Deduct 1834 from 2739 and we're left with 905.
Grab the next digit (1) from the dividend, add it to 905, then carry on: 9051 / 917

On to step 8:
If we divide 9051 by 917, we get 9 and a remainder of 798.
Put 9 as the next digit of the answer. 
Result so far: 59029.0
Subtracting 8253 from 9051 leaves us with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Let's proceed to step 9:
When dividing 7980 by 917, we get 8 with a remainder of 644.
Use 8 as the next digit of our solution. 
Result so far: 59029.8
Deduct 7336 from 7980 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Advancing to step 10:
917 goes into 6440 7 times with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 59029.87
Deduct 6419 from 6440 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
The number 917 fits into 210 0 times, leaving a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 59029.87
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 12:
The number 917 fits into 2100 2 times, leaving a remainder of 266.
The number 2 becomes the next digit in our result. 
Result so far: 59029.8702
Subtract 1834 from 2100 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 13:
2660 divided by 917 is 2 with a remainder of 826.
The number 2 becomes the next digit in our result. 
Result so far: 59029.87022
Subtract 1834 from 2660 to get 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

After the division, we end up with 59029.87022 and a remainder of 0.000826.
