Let's divide 42056934 by 398
The aim is to understand the frequency of 398 in 42056934.

Moving on to step 1:
398 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 398

On to step 2:
398 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 398

Let's proceed to step 3:
If we divide 420 by 398, we get 1 and a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
If we take 398 away from 420, we end up with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 398

Let's proceed to step 4:
If we divide 225 by 398, we get 0 and a remainder of 225.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 225 after subtracting 0 from 225.
Include the next digit (6) from the dividend after 225, then repeat: 2256 / 398

Advancing to step 5:
When dividing 2256 by 398, we get 5 with a remainder of 266.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
If we take 1990 away from 2256, we end up with 266.
Append the next digit (9) from the dividend to 266 and continue with: 2669 / 398

On to step 6:
When dividing 2669 by 398, we get 6 with a remainder of 281.
Put 6 as the next digit of the answer. 
Result so far: 1056.0
If we subtract 2388 from 2669, we get 281.
Grab the next digit (3) from the dividend, add it to 281, then carry on: 2813 / 398

Let's proceed to step 7:
The number 398 fits into 2813 7 times, leaving a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 10567.0
Subtracting 2786 from 2813 leaves us with 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 398

Step 8:
When dividing 274 by 398, we get 0 with a remainder of 274.
The next digit of our result is 0. 
Result so far: 105670.0
If we subtract 0 from 274, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 9:
398 goes into 2740 6 times with a remainder of 352.
The next digit of our result is 6. 
Result so far: 105670.6
Subtract 2388 from 2740 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 10:
If we divide 3520 by 398, we get 8 and a remainder of 336.
Use 8 as the next digit of our solution. 
Result so far: 105670.68
Deduct 3184 from 3520 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 11:
If we divide 3360 by 398, we get 8 and a remainder of 176.
Put 8 as the next digit of the answer. 
Result so far: 105670.688
Subtracting 3184 from 3360 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final result is 105670.688 with a remainder of 0.0176.
