We're dividing 374199 by 84 
The aim is to understand the frequency of 84 in 374199.

Let's proceed to step 1:
When dividing 3 by 84, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 84

Let's proceed to step 2:
If we divide 37 by 84, we get 0 and a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 84

Moving on to step 3:
If we divide 374 by 84, we get 4 and a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 336 from 374 and we're left with 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 84

Moving on to step 4:
84 goes into 381 4 times with a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Deduct 336 from 381 and we're left with 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 84

Moving on to step 5:
When dividing 459 by 84, we get 5 with a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 445.0
Subtract 420 from 459 to get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 84

Step 6:
The number 84 fits into 399 4 times, leaving a remainder of 63.
Record the quotient 4 as the next digit in the result. 
Result so far: 4454.0
Deduct 336 from 399 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 7:
630 divided by 84 is 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 4454.7
Subtract 588 from 630 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
If we divide 420 by 84, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4454.75
Deduct 420 from 420 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
84 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4454.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
84 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 4454.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 4454.75, and the remainder is 0.0.
