Let's divide 83675654 by 84
The aim is to understand the frequency of 84 in 83675654.

Advancing to step 1:
8 divided by 84 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 84

Advancing to step 2:
When dividing 83 by 84, we get 0 with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Append the next digit (6) from the dividend to 83 and continue with: 836 / 84

Advancing to step 3:
If we divide 836 by 84, we get 9 and a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 756 from 836 leaves us with 80.
Include the next digit (7) from the dividend after 80, then repeat: 807 / 84

On to step 4:
If we divide 807 by 84, we get 9 and a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we subtract 756 from 807, we get 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 84

Step 5:
When dividing 515 by 84, we get 6 with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 996.0
Subtract 504 from 515 to get 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 84

Let's proceed to step 6:
The number 84 fits into 116 1 times, leaving a remainder of 32.
The next digit of our result is 1. 
Result so far: 9961.0
Subtract 84 from 116 to get 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 84

Advancing to step 7:
If we divide 325 by 84, we get 3 and a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 99613.0
The remainder is 73 after subtracting 252 from 325.
Grab the next digit (4) from the dividend, add it to 73, then carry on: 734 / 84

Step 8:
If we divide 734 by 84, we get 8 and a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 996138.0
If we take 672 away from 734, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
84 goes into 620 7 times with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 996138.7
Subtracting 588 from 620 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
The number 84 fits into 320 3 times, leaving a remainder of 68.
The next digit of our result is 3. 
Result so far: 996138.73
Deduct 252 from 320 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
84 can be fit into 680 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 996138.738
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
84 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 996138.738
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
84 goes into 800 9 times with a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 996138.73809
If we take 756 away from 800, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
440 divided by 84 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 996138.738095
Deduct 420 from 440 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 996138.7380952
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 16:
The number 84 fits into 320 3 times, leaving a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 996138.73809523
The remainder is 68 after subtracting 252 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 996138.73809523 and a remainder of 6.8e-08.
