We divide 373558 by 42
The aim is to understand the frequency of 42 in 373558.

Going ahead to step 1:
42 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 42

On to step 2:
If we divide 37 by 42, we get 0 and a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 42

Going ahead to step 3:
42 can be fit into 373 8 times, resulting in a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 336 from 373 and we're left with 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 42

Going ahead to step 4:
42 can be fit into 375 8 times, resulting in a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 88.0
If we subtract 336 from 375, we get 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 42

On to step 5:
42 can be fit into 395 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 889.0
If we take 378 away from 395, we end up with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 42

Going ahead to step 6:
178 divided by 42 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 8894.0
The remainder is 10 after subtracting 168 from 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 8894.2
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
If we divide 160 by 42, we get 3 and a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 8894.23
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 8894.238
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
When dividing 40 by 42, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 8894.238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
When dividing 400 by 42, we get 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 8894.23809
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
If we divide 220 by 42, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 8894.238095
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
100 divided by 42 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 8894.2380952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 8894.23809523
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 8894.23809523 and a remainder of 3.4e-08.
