We're dividing 12365601 by 913 
The aim is to understand the frequency of 913 in 12365601.

Moving on to step 1:
If we divide 1 by 913, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 913

Going ahead to step 2:
The number 913 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 913

Moving on to step 3:
If we divide 123 by 913, we get 0 and a remainder of 123.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 123 leaves us with 123.
Append the next digit (6) from the dividend to 123 and continue with: 1236 / 913

On to step 4:
If we divide 1236 by 913, we get 1 and a remainder of 323.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 323 after subtracting 913 from 1236.
Grab the next digit (5) from the dividend, add it to 323, then carry on: 3235 / 913

Moving on to step 5:
3235 divided by 913 is 3 with a remainder of 496.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 2739 from 3235 and we're left with 496.
Grab the next digit (6) from the dividend, add it to 496, then carry on: 4966 / 913

Moving on to step 6:
If we divide 4966 by 913, we get 5 and a remainder of 401.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Deduct 4565 from 4966 and we're left with 401.
Append the next digit (0) from the dividend to 401 and continue with: 4010 / 913

Let's proceed to step 7:
The number 913 fits into 4010 4 times, leaving a remainder of 358.
Record the quotient 4 as the next digit in the result. 
Result so far: 1354.0
Subtract 3652 from 4010 to get 358.
Bring next digit (1) of the dividend behind the 358 and repeat the process: 3581 / 913

On to step 8:
913 can be fit into 3581 3 times, resulting in a remainder of 842.
Write down 3 as next digit of the result. 
Result so far: 13543.0
If we subtract 2739 from 3581, we get 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Advancing to step 9:
When dividing 8420 by 913, we get 9 with a remainder of 203.
The number 9 becomes the next digit in our result. 
Result so far: 13543.9
Subtract 8217 from 8420 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 10:
The number 913 fits into 2030 2 times, leaving a remainder of 204.
Put 2 as the next digit of the answer. 
Result so far: 13543.92
If we subtract 1826 from 2030, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 11:
If we divide 2040 by 913, we get 2 and a remainder of 214.
Record the quotient 2 as the next digit in the result. 
Result so far: 13543.922
Subtracting 1826 from 2040 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

The quotient of the division is 13543.922, and the remainder is 0.0214.
