Let's divide 71590927 by 913
The aim is to understand the frequency of 913 in 71590927.

On to step 1:
If we divide 7 by 913, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 913

Let's proceed to step 2:
913 can be fit into 71 0 times, resulting in a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 913

Advancing to step 3:
The number 913 fits into 715 0 times, leaving a remainder of 715.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 715, we end up with 715.
Append the next digit (9) from the dividend to 715 and continue with: 7159 / 913

Going ahead to step 4:
If we divide 7159 by 913, we get 7 and a remainder of 768.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 768 after subtracting 6391 from 7159.
Take the next digit (0) from the dividend and append it to 768, then repeat: 7680 / 913

Let's proceed to step 5:
The number 913 fits into 7680 8 times, leaving a remainder of 376.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
The remainder is 376 after subtracting 7304 from 7680.
Bring next digit (9) of the dividend behind the 376 and repeat the process: 3769 / 913

Moving on to step 6:
3769 divided by 913 is 4 with a remainder of 117.
The next digit of our result is 4. 
Result so far: 784.0
Subtract 3652 from 3769 to get 117.
Include the next digit (2) from the dividend after 117, then repeat: 1172 / 913

Moving on to step 7:
913 goes into 1172 1 times with a remainder of 259.
Use 1 as the next digit of our solution. 
Result so far: 7841.0
Deduct 913 from 1172 and we're left with 259.
Fetch the next digit (7) from the dividend, attach it to 259 and continue: 2597 / 913

On to step 8:
913 goes into 2597 2 times with a remainder of 771.
The next digit of our result is 2. 
Result so far: 78412.0
Subtract 1826 from 2597 to get 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

Going ahead to step 9:
The number 913 fits into 7710 8 times, leaving a remainder of 406.
Use 8 as the next digit of our solution. 
Result so far: 78412.8
Deduct 7304 from 7710 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 10:
The number 913 fits into 4060 4 times, leaving a remainder of 408.
The next digit of our result is 4. 
Result so far: 78412.84
Subtracting 3652 from 4060 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 11:
913 can be fit into 4080 4 times, resulting in a remainder of 428.
The next digit of our result is 4. 
Result so far: 78412.844
Subtracting 3652 from 4080 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

After the division, we end up with 78412.844 and a remainder of 0.0428.
