We look at the division of 87126241 by 600 
The aim is to understand the frequency of 600 in 87126241.

Let's proceed to step 1:
The number 600 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 600

Let's proceed to step 2:
The number 600 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 600

Moving on to step 3:
When dividing 871 by 600, we get 1 with a remainder of 271.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 600 from 871 and we're left with 271.
Take the next digit (2) from the dividend and append it to 271, then repeat: 2712 / 600

On to step 4:
The number 600 fits into 2712 4 times, leaving a remainder of 312.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 2400 from 2712 and we're left with 312.
Append the next digit (6) from the dividend to 312 and continue with: 3126 / 600

Going ahead to step 5:
3126 divided by 600 is 5 with a remainder of 126.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
Subtracting 3000 from 3126 leaves us with 126.
Fetch the next digit (2) from the dividend, attach it to 126 and continue: 1262 / 600

Step 6:
The number 600 fits into 1262 2 times, leaving a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 1452.0
The remainder is 62 after subtracting 1200 from 1262.
Grab the next digit (4) from the dividend, add it to 62, then carry on: 624 / 600

Moving on to step 7:
When dividing 624 by 600, we get 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 14521.0
The remainder is 24 after subtracting 600 from 624.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 600

Step 8:
The number 600 fits into 241 0 times, leaving a remainder of 241.
The number 0 becomes the next digit in our result. 
Result so far: 145210.0
The remainder is 241 after subtracting 0 from 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

On to step 9:
When dividing 2410 by 600, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 145210.4
Deduct 2400 from 2410 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
The number 600 fits into 100 0 times, leaving a remainder of 100.
The next digit of our result is 0. 
Result so far: 145210.4
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
600 goes into 1000 1 times with a remainder of 400.
The next digit of our result is 1. 
Result so far: 145210.401
The remainder is 400 after subtracting 600 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 12:
600 goes into 4000 6 times with a remainder of 400.
Put 6 as the next digit of the answer. 
Result so far: 145210.4016
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.

Advancing to step 13:
When dividing 4000 by 600, we get 6 with a remainder of 400.
The next digit of our result is 6. 
Result so far: 145210.40166
If we subtract 3600 from 4000, 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.

The final result is 145210.40166 with a remainder of 0.0004.
