74134855 divided by 600 
The aim is to understand the frequency of 600 in 74134855.

On to step 1:
If we divide 7 by 600, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 600

Let's proceed to step 2:
The number 600 fits into 74 0 times, leaving a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Grab the next digit (1) from the dividend, add it to 74, then carry on: 741 / 600

Advancing to step 3:
600 goes into 741 1 times with a remainder of 141.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 600 from 741, we get 141.
Grab the next digit (3) from the dividend, add it to 141, then carry on: 1413 / 600

Going ahead to step 4:
1413 divided by 600 is 2 with a remainder of 213.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1200 from 1413 and we're left with 213.
Append the next digit (4) from the dividend to 213 and continue with: 2134 / 600

Moving on to step 5:
If we divide 2134 by 600, we get 3 and a remainder of 334.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Deduct 1800 from 2134 and we're left with 334.
Include the next digit (8) from the dividend after 334, then repeat: 3348 / 600

On to step 6:
The number 600 fits into 3348 5 times, leaving a remainder of 348.
Put 5 as the next digit of the answer. 
Result so far: 1235.0
If we subtract 3000 from 3348, we get 348.
Append the next digit (5) from the dividend to 348 and continue with: 3485 / 600

Moving on to step 7:
600 goes into 3485 5 times with a remainder of 485.
The number 5 becomes the next digit in our result. 
Result so far: 12355.0
Subtract 3000 from 3485 to get 485.
Append the next digit (5) from the dividend to 485 and continue with: 4855 / 600

Moving on to step 8:
When dividing 4855 by 600, we get 8 with a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 123558.0
If we subtract 4800 from 4855, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 9:
600 goes into 550 0 times with a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 123558.0
Deduct 0 from 550 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 10:
When dividing 5500 by 600, we get 9 with a remainder of 100.
The number 9 becomes the next digit in our result. 
Result so far: 123558.09
Deduct 5400 from 5500 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
1000 divided by 600 is 1 with a remainder of 400.
Put 1 as the next digit of the answer. 
Result so far: 123558.091
If we subtract 600 from 1000, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 12:
The number 600 fits into 4000 6 times, leaving a remainder of 400.
The number 6 becomes the next digit in our result. 
Result so far: 123558.0916
Subtracting 3600 from 4000 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 13:
If we divide 4000 by 600, we get 6 and a remainder of 400.
Use 6 as the next digit of our solution. 
Result so far: 123558.09166
Deduct 3600 from 4000 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 123558.09166, and the remainder is 0.0004.
