67157861 ÷ 84 
The aim is to understand the frequency of 84 in 67157861.

On to step 1:
If we divide 6 by 84, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 84

Going ahead to step 2:
84 goes into 67 0 times with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Take the next digit (1) from the dividend and append it to 67, then repeat: 671 / 84

Let's proceed to step 3:
The number 84 fits into 671 7 times, leaving a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 588 from 671 and we're left with 83.
Include the next digit (5) from the dividend after 83, then repeat: 835 / 84

Let's proceed to step 4:
When dividing 835 by 84, we get 9 with a remainder of 79.
The next digit of our result is 9. 
Result so far: 79.0
If we subtract 756 from 835, we get 79.
Fetch the next digit (7) from the dividend, attach it to 79 and continue: 797 / 84

Going ahead to step 5:
The number 84 fits into 797 9 times, leaving a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 799.0
The remainder is 41 after subtracting 756 from 797.
Fetch the next digit (8) from the dividend, attach it to 41 and continue: 418 / 84

On to step 6:
84 can be fit into 418 4 times, resulting in a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 7994.0
Subtract 336 from 418 to get 82.
Bring next digit (6) of the dividend behind the 82 and repeat the process: 826 / 84

Going ahead to step 7:
When dividing 826 by 84, we get 9 with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 79949.0
If we take 756 away from 826, we end up with 70.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 84

Going ahead to step 8:
If we divide 701 by 84, we get 8 and a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 799498.0
Deduct 672 from 701 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
The number 84 fits into 290 3 times, leaving a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 799498.3
Subtract 252 from 290 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
When dividing 380 by 84, we get 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 799498.34
If we take 336 away from 380, 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.

On to step 11:
The number 84 fits into 440 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 799498.345
The remainder is 20 after subtracting 420 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
The number 84 fits into 200 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 799498.3452
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.

Going ahead to step 13:
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: 799498.34523
Subtract 252 from 320 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 14:
If we divide 680 by 84, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 799498.345238
Deduct 672 from 680 and we're left 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 15:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 799498.345238
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 16:
The number 84 fits into 800 9 times, leaving a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 799498.34523809
If we subtract 756 from 800, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 799498.34523809 and a remainder of 4.4e-08.
