345112 divided by 84 
The aim is to understand the frequency of 84 in 345112.

Advancing to step 1:
The number 84 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 84

On to step 2:
84 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 84

Step 3:
The number 84 fits into 345 4 times, leaving a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 336 from 345 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 84

Let's proceed to step 4:
If we divide 91 by 84, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 84 from 91 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 84

Advancing to step 5:
If we divide 71 by 84, we get 0 and a remainder of 71.
The next digit of our result is 0. 
Result so far: 410.0
Subtract 0 from 71 to get 71.
Fetch the next digit (2) from the dividend, attach it to 71 and continue: 712 / 84

Going ahead to step 6:
If we divide 712 by 84, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 4108.0
Subtracting 672 from 712 leaves us with 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 7:
400 divided by 84 is 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 4108.4
Subtracting 336 from 400 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
If we divide 640 by 84, we get 7 and a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 4108.47
Deduct 588 from 640 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
520 divided by 84 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 4108.476
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
The number 84 fits into 160 1 times, leaving a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 4108.4761
Subtracting 84 from 160 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 11:
760 divided by 84 is 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 4108.47619
If we subtract 756 from 760, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
84 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4108.47619
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 13:
When dividing 400 by 84, we get 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 4108.4761904
Subtracting 336 from 400 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
When dividing 640 by 84, we get 7 with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 4108.47619047
If we take 588 away from 640, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 4108.47619047, and the remainder is 5.2e-08.
