350069 divided by 84 
The aim is to understand the frequency of 84 in 350069.

Going ahead to step 1:
If we divide 3 by 84, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 84

Going ahead to step 2:
When dividing 35 by 84, we get 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 84

Moving on to step 3:
350 divided by 84 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 336 from 350 and we're left with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 84

Let's proceed to step 4:
84 goes into 140 1 times with a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
The remainder is 56 after subtracting 84 from 140.
Append the next digit (6) from the dividend to 56 and continue with: 566 / 84

Going ahead to step 5:
If we divide 566 by 84, we get 6 and a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 416.0
Deduct 504 from 566 and we're left with 62.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 84

Let's proceed to step 6:
When dividing 629 by 84, we get 7 with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 4167.0
Deduct 588 from 629 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
84 goes into 410 4 times with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 4167.4
Subtract 336 from 410 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 8:
If we divide 740 by 84, we get 8 and a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 4167.48
If we subtract 672 from 740, we 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.

Advancing to step 9:
84 can be fit into 680 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 4167.488
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.

The quotient of the division is 4167.488, and the remainder is 0.0008.
