371148 ÷ 42 
The aim is to understand the frequency of 42 in 371148.

Advancing to step 1:
The number 42 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 42

Going ahead to step 2:
When dividing 37 by 42, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 42

Moving on to step 3:
The number 42 fits into 371 8 times, leaving a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 336 from 371 to get 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 42

Moving on to step 4:
42 can be fit into 351 8 times, resulting in a remainder of 15.
The next digit of our result is 8. 
Result so far: 88.0
If we take 336 away from 351, we end up with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 42

Going ahead to step 5:
42 can be fit into 154 3 times, resulting in a remainder of 28.
The next digit of our result is 3. 
Result so far: 883.0
If we take 126 away from 154, we end up with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 42

Advancing to step 6:
The number 42 fits into 288 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 8836.0
If we take 252 away from 288, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
When dividing 360 by 42, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 8836.8
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
240 divided by 42 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 8836.85
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
If we divide 300 by 42, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 8836.857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
When dividing 60 by 42, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 8836.8571
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 8836.85714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 8836.857142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
360 divided by 42 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 8836.8571428
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
If we divide 240 by 42, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8836.85714285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 8836.85714285 with a remainder of 3e-08.
