We're dividing 616589 by 42 
The aim is to understand the frequency of 42 in 616589.

Step 1:
6 divided by 42 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 42

Step 2:
If we divide 61 by 42, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 42 away from 61, we end up with 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 42

Going ahead to step 3:
If we divide 196 by 42, we get 4 and a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 168 from 196 and we're left with 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 42

Going ahead to step 4:
The number 42 fits into 285 6 times, leaving a remainder of 33.
Put 6 as the next digit of the answer. 
Result so far: 146.0
The remainder is 33 after subtracting 252 from 285.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 42

Moving on to step 5:
338 divided by 42 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 1468.0
Subtracting 336 from 338 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 42

Let's proceed to step 6:
The number 42 fits into 29 0 times, leaving a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 14680.0
Subtract 0 from 29 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.

Moving on to step 7:
290 divided by 42 is 6 with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 14680.6
Deduct 252 from 290 and we're left 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.

Going ahead to step 8:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 14680.69
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 14680.69
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 14680.6904
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
If we divide 320 by 42, we get 7 and a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 14680.69047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
When dividing 260 by 42, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 14680.690476
Deduct 252 from 260 and we're left 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.

Moving on to step 13:
42 goes into 80 1 times with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 14680.6904761
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
If we divide 380 by 42, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 14680.69047619
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 14680.69047619, with a leftover of 2e-09.
