Let's divide 553615 by 42
The aim is to understand the frequency of 42 in 553615.

Step 1:
42 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 42

Advancing to step 2:
When dividing 55 by 42, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 13 after subtracting 42 from 55.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 42

Going ahead to step 3:
The number 42 fits into 133 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 126 from 133 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 42

Moving on to step 4:
If we divide 76 by 42, we get 1 and a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 131.0
If we subtract 42 from 76, we get 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 42

Let's proceed to step 5:
When dividing 341 by 42, we get 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 1318.0
If we take 336 away from 341, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 42

Let's proceed to step 6:
If we divide 55 by 42, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 13181.0
The remainder is 13 after subtracting 42 from 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
When dividing 130 by 42, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 13181.3
Subtract 126 from 130 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.

Moving on to step 8:
42 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 13181.3
If we take 0 away from 40, we end up 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.

Moving on to step 9:
42 goes into 400 9 times with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 13181.309
If we take 378 away from 400, we end up 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.

Step 10:
42 can be fit into 220 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 13181.3095
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
42 goes into 100 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 13181.30952
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
42 goes into 160 3 times with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 13181.309523
Subtracting 126 from 160 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.

Let's proceed to step 13:
If we divide 340 by 42, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 13181.3095238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
If we divide 40 by 42, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 13181.3095238
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.

The final outcome is 13181.3095238, with a leftover of 4e-08.
