We look at the division of 126359 by 53 
The aim is to understand the frequency of 53 in 126359.

Advancing to step 1:
53 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 53

Going ahead to step 2:
If we divide 12 by 53, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 53

Going ahead to step 3:
When dividing 126 by 53, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 106 from 126 to get 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 53

Let's proceed to step 4:
203 divided by 53 is 3 with a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtracting 159 from 203 leaves us with 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 53

Going ahead to step 5:
When dividing 445 by 53, we get 8 with a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 238.0
Subtract 424 from 445 to get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 53

Advancing to step 6:
53 goes into 219 4 times with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 2384.0
Subtracting 212 from 219 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 53, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 2384.1
Deduct 53 from 70 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
170 divided by 53 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 2384.13
Deduct 159 from 170 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
If we divide 110 by 53, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2384.132
Subtract 106 from 110 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
When dividing 40 by 53, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 2384.132
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
400 divided by 53 is 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 2384.13207
Subtract 371 from 400 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 12:
When dividing 290 by 53, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2384.132075
If we take 265 away from 290, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 13:
250 divided by 53 is 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 2384.1320754
If we take 212 away from 250, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
53 goes into 380 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 2384.13207547
The remainder is 9 after subtracting 371 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 2384.13207547, and the remainder is 9e-09.
