443252 ÷ 42 
The aim is to understand the frequency of 42 in 443252.

Advancing to step 1:
4 divided by 42 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 42

Moving on to step 2:
44 divided by 42 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 42 from 44 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 42

Let's proceed to step 3:
42 goes into 23 0 times with a remainder of 23.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 23 and we're left with 23.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 42

Let's proceed to step 4:
232 divided by 42 is 5 with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Subtract 210 from 232 to get 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 42

Moving on to step 5:
The number 42 fits into 225 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1055.0
Deduct 210 from 225 and we're left with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 42

On to step 6:
If we divide 152 by 42, we get 3 and a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 10553.0
The remainder is 26 after subtracting 126 from 152.
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 7:
42 goes into 260 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 10553.6
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.

Going ahead to step 8:
42 can be fit into 80 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 10553.61
If we take 42 away from 80, 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.

Advancing to step 9:
42 goes into 380 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 10553.619
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.

Moving on to step 10:
20 divided by 42 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10553.619
Subtract 0 from 20 to 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.

Going ahead to step 11:
200 divided by 42 is 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 10553.61904
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.

On to step 12:
When dividing 320 by 42, we get 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 10553.619047
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
260 divided by 42 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 10553.6190476
The remainder is 8 after subtracting 252 from 260.
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 14:
When dividing 80 by 42, we get 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 10553.61904761
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.

After the division, we end up with 10553.61904761 and a remainder of 3.8e-08.
