93457 divided by 42 
The aim is to understand the frequency of 42 in 93457.

Going ahead to step 1:
The number 42 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 42

Step 2:
93 divided by 42 is 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 84 from 93 to get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 42

Advancing to step 3:
When dividing 94 by 42, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 84 from 94 and we're left with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 42

Advancing to step 4:
The number 42 fits into 105 2 times, leaving a remainder of 21.
The next digit of our result is 2. 
Result so far: 222.0
If we subtract 84 from 105, we get 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 42

Advancing to step 5:
217 divided by 42 is 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 2225.0
If we subtract 210 from 217, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 6:
If we divide 70 by 42, we get 1 and a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 2225.1
Deduct 42 from 70 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
When dividing 280 by 42, we get 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 2225.16
Subtract 252 from 280 to 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.

On to step 8:
When dividing 280 by 42, we get 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 2225.166
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 2225.166 and a remainder of 0.0028.
