Let's divide 423045 by 85
The aim is to understand the frequency of 85 in 423045.

Moving on to step 1:
The number 85 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 85

Let's proceed to step 2:
If we divide 42 by 85, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 85

On to step 3:
423 divided by 85 is 4 with a remainder of 83.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 340 from 423 and we're left with 83.
Take the next digit (0) from the dividend and append it to 83, then repeat: 830 / 85

Moving on to step 4:
85 goes into 830 9 times with a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we subtract 765 from 830, we get 65.
Grab the next digit (4) from the dividend, add it to 65, then carry on: 654 / 85

Step 5:
When dividing 654 by 85, we get 7 with a remainder of 59.
The next digit of our result is 7. 
Result so far: 497.0
Subtracting 595 from 654 leaves us with 59.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 85

Moving on to step 6:
If we divide 595 by 85, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 4977.0
Subtract 595 from 595 to 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.

Moving on to step 7:
85 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4977.0
Subtract 0 from 0 to 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.

On to step 8:
0 divided by 85 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4977.0
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.

After the division, we end up with 4977.0 and a remainder of 0.0.
