We divide 45120369 by 891
The aim is to understand the frequency of 891 in 45120369.

Moving on to step 1:
If we divide 4 by 891, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 891

Going ahead to step 2:
The number 891 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 891

Moving on to step 3:
891 can be fit into 451 0 times, resulting in a remainder of 451.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 451 after subtracting 0 from 451.
Bring next digit (2) of the dividend behind the 451 and repeat the process: 4512 / 891

On to step 4:
891 goes into 4512 5 times with a remainder of 57.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 4455 from 4512 to get 57.
Grab the next digit (0) from the dividend, add it to 57, then carry on: 570 / 891

Let's proceed to step 5:
570 divided by 891 is 0 with a remainder of 570.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 570 and we're left with 570.
Append the next digit (3) from the dividend to 570 and continue with: 5703 / 891

Moving on to step 6:
If we divide 5703 by 891, we get 6 and a remainder of 357.
The number 6 becomes the next digit in our result. 
Result so far: 506.0
Subtract 5346 from 5703 to get 357.
Include the next digit (6) from the dividend after 357, then repeat: 3576 / 891

Step 7:
3576 divided by 891 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 5064.0
The remainder is 12 after subtracting 3564 from 3576.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 891

Going ahead to step 8:
891 goes into 129 0 times with a remainder of 129.
The next digit of our result is 0. 
Result so far: 50640.0
If we take 0 away from 129, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 9:
The number 891 fits into 1290 1 times, leaving a remainder of 399.
Record the quotient 1 as the next digit in the result. 
Result so far: 50640.1
The remainder is 399 after subtracting 891 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

On to step 10:
891 can be fit into 3990 4 times, resulting in a remainder of 426.
The number 4 becomes the next digit in our result. 
Result so far: 50640.14
Deduct 3564 from 3990 and we're left with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 11:
If we divide 4260 by 891, we get 4 and a remainder of 696.
The next digit of our result is 4. 
Result so far: 50640.144
Subtracting 3564 from 4260 leaves us with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

After the division, we end up with 50640.144 and a remainder of 0.0696.
