We look at the division of 83412790 by 600 
The aim is to understand the frequency of 600 in 83412790.

Step 1:
If we divide 8 by 600, we get 0 and 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.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 600

Advancing to step 2:
600 goes into 83 0 times with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Bring next digit (4) of the dividend behind the 83 and repeat the process: 834 / 600

Let's proceed to step 3:
834 divided by 600 is 1 with a remainder of 234.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 600 from 834, we get 234.
Grab the next digit (1) from the dividend, add it to 234, then carry on: 2341 / 600

Let's proceed to step 4:
600 goes into 2341 3 times with a remainder of 541.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1800 away from 2341, we end up with 541.
Bring next digit (2) of the dividend behind the 541 and repeat the process: 5412 / 600

On to step 5:
The number 600 fits into 5412 9 times, leaving a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 139.0
If we subtract 5400 from 5412, we get 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 600

Advancing to step 6:
When dividing 127 by 600, we get 0 with a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 1390.0
Deduct 0 from 127 and we're left with 127.
Fetch the next digit (9) from the dividend, attach it to 127 and continue: 1279 / 600

Going ahead to step 7:
1279 divided by 600 is 2 with a remainder of 79.
The next digit of our result is 2. 
Result so far: 13902.0
Subtract 1200 from 1279 to get 79.
Take the next digit (0) from the dividend and append it to 79, then repeat: 790 / 600

Going ahead to step 8:
The number 600 fits into 790 1 times, leaving a remainder of 190.
The number 1 becomes the next digit in our result. 
Result so far: 139021.0
If we subtract 600 from 790, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 9:
The number 600 fits into 1900 3 times, leaving a remainder of 100.
The next digit of our result is 3. 
Result so far: 139021.3
Deduct 1800 from 1900 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.

On to step 10:
When dividing 1000 by 600, we get 1 with a remainder of 400.
Put 1 as the next digit of the answer. 
Result so far: 139021.31
Subtracting 600 from 1000 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.

Moving on to step 11:
When dividing 4000 by 600, we get 6 with a remainder of 400.
Put 6 as the next digit of the answer. 
Result so far: 139021.316
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 12:
600 goes into 4000 6 times with a remainder of 400.
The next digit of our result is 6. 
Result so far: 139021.3166
If we take 3600 away from 4000, we end up 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.

Our division results in 139021.3166 with a remaining 0.004.
