87483320 divided by 53 
The aim is to understand the frequency of 53 in 87483320.

Advancing to step 1:
53 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 53

Step 2:
53 can be fit into 87 1 times, resulting in a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 53 from 87 to get 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 53

Going ahead to step 3:
If we divide 344 by 53, we get 6 and a remainder of 26.
The next digit of our result is 6. 
Result so far: 16.0
If we take 318 away from 344, we end up with 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 53

Going ahead to step 4:
If we divide 268 by 53, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 165.0
Deduct 265 from 268 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 53

Advancing to step 5:
53 can be fit into 33 0 times, resulting in a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 1650.0
If we take 0 away from 33, we end up with 33.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 53

On to step 6:
If we divide 333 by 53, we get 6 and a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 16506.0
If we take 318 away from 333, we end up with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 53

Moving on to step 7:
53 can be fit into 152 2 times, resulting in a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 165062.0
If we subtract 106 from 152, we get 46.
Bring next digit (0) of the dividend behind the 46 and repeat the process: 460 / 53

Going ahead to step 8:
When dividing 460 by 53, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 1650628.0
The remainder is 36 after subtracting 424 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
When dividing 360 by 53, we get 6 with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 1650628.6
The remainder is 42 after subtracting 318 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
The number 53 fits into 420 7 times, leaving a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 1650628.67
If we subtract 371 from 420, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 11:
490 divided by 53 is 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 1650628.679
If we take 477 away from 490, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
130 divided by 53 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 1650628.6792
The remainder is 24 after subtracting 106 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
53 goes into 240 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 1650628.67924
If we subtract 212 from 240, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
When dividing 280 by 53, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1650628.679245
Deduct 265 from 280 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 15:
The number 53 fits into 150 2 times, leaving a remainder of 44.
The next digit of our result is 2. 
Result so far: 1650628.6792452
Subtract 106 from 150 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 16:
The number 53 fits into 440 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 1650628.67924528
Subtract 424 from 440 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 1650628.67924528, with a leftover of 1.6e-08.
