347993 divided by 4 
The aim is to understand the frequency of 4 in 347993.

Step 1:
When dividing 3 by 4, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 4

Going ahead to step 2:
If we divide 34 by 4, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 32 from 34 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 4

Advancing to step 3:
When dividing 27 by 4, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtract 24 from 27 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 4

Going ahead to step 4:
39 divided by 4 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 869.0
Subtract 36 from 39 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 4

Moving on to step 5:
4 can be fit into 39 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 8699.0
The remainder is 3 after subtracting 36 from 39.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 4

Advancing to step 6:
If we divide 33 by 4, we get 8 and a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 86998.0
If we subtract 32 from 33, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 4, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 86998.2
If we subtract 8 from 10, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
4 goes into 20 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 86998.25
Deduct 20 from 20 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.

Moving on to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 86998.25
The remainder is 0 after subtracting 0 from 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 10:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 86998.25
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.

The quotient of the division is 86998.25, and the remainder is 0.0.
