Let's divide 869744 by 53
The aim is to understand the frequency of 53 in 869744.

Going ahead to step 1:
8 divided by 53 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 53

On to step 2:
The number 53 fits into 86 1 times, leaving a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 53 from 86 leaves us with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 53

Moving on to step 3:
339 divided by 53 is 6 with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 21 after subtracting 318 from 339.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 53

On to step 4:
53 can be fit into 217 4 times, resulting in a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 164.0
Deduct 212 from 217 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 53

Let's proceed to step 5:
53 can be fit into 54 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1641.0
If we subtract 53 from 54, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 53

On to step 6:
14 divided by 53 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 16410.0
Deduct 0 from 14 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
The number 53 fits into 140 2 times, leaving a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 16410.2
Subtracting 106 from 140 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
When dividing 340 by 53, we get 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 16410.26
Deduct 318 from 340 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
If we divide 220 by 53, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 16410.264
If we take 212 away from 220, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 53 is 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 16410.2641
If we take 53 away from 80, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 11:
When dividing 270 by 53, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 16410.26415
Deduct 265 from 270 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
53 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 16410.26415
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
The number 53 fits into 500 9 times, leaving a remainder of 23.
The next digit of our result is 9. 
Result so far: 16410.2641509
Subtract 477 from 500 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 14:
If we divide 230 by 53, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 16410.26415094
Subtract 212 from 230 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 16410.26415094, with a leftover of 1.8e-08.
