We divide 725951 by 42
The aim is to understand the frequency of 42 in 725951.

Going ahead to step 1:
If we divide 7 by 42, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 42

On to step 2:
The number 42 fits into 72 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 42 from 72 leaves us with 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 42

Advancing to step 3:
The number 42 fits into 305 7 times, leaving a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 294 from 305 and we're left with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 42

Moving on to step 4:
119 divided by 42 is 2 with a remainder of 35.
The next digit of our result is 2. 
Result so far: 172.0
If we take 84 away from 119, we end up with 35.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 42

On to step 5:
355 divided by 42 is 8 with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 1728.0
If we subtract 336 from 355, we get 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 42

Moving on to step 6:
191 divided by 42 is 4 with a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 17284.0
Subtracting 168 from 191 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
230 divided by 42 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 17284.5
If we take 210 away from 230, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 42 fits into 200 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 17284.54
Subtract 168 from 200 to 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.

Step 9:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 17284.547
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.

Let's proceed to step 10:
When dividing 260 by 42, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 17284.5476
If we take 252 away from 260, 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.

Advancing to step 11:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 17284.54761
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.

On to step 12:
380 divided by 42 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 17284.547619
If we take 378 away from 380, we end up 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.

Going ahead to step 13:
The number 42 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 17284.547619
The remainder is 20 after subtracting 0 from 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 14:
The number 42 fits into 200 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 17284.54761904
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 17284.54761904, and the remainder is 3.2e-08.
