71145890 divided by 600 
The aim is to understand the frequency of 600 in 71145890.

Moving on to step 1:
If we divide 7 by 600, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 600

Let's proceed to step 2:
When dividing 71 by 600, we get 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Append the next digit (1) from the dividend to 71 and continue with: 711 / 600

Let's proceed to step 3:
When dividing 711 by 600, we get 1 with a remainder of 111.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 600 from 711 and we're left with 111.
Take the next digit (4) from the dividend and append it to 111, then repeat: 1114 / 600

Let's proceed to step 4:
When dividing 1114 by 600, we get 1 with a remainder of 514.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 514 after subtracting 600 from 1114.
Take the next digit (5) from the dividend and append it to 514, then repeat: 5145 / 600

On to step 5:
5145 divided by 600 is 8 with a remainder of 345.
Use 8 as the next digit of our solution. 
Result so far: 118.0
Subtracting 4800 from 5145 leaves us with 345.
Bring next digit (8) of the dividend behind the 345 and repeat the process: 3458 / 600

Moving on to step 6:
600 can be fit into 3458 5 times, resulting in a remainder of 458.
Record the quotient 5 as the next digit in the result. 
Result so far: 1185.0
If we subtract 3000 from 3458, we get 458.
Include the next digit (9) from the dividend after 458, then repeat: 4589 / 600

Going ahead to step 7:
When dividing 4589 by 600, we get 7 with a remainder of 389.
The number 7 becomes the next digit in our result. 
Result so far: 11857.0
Deduct 4200 from 4589 and we're left with 389.
Take the next digit (0) from the dividend and append it to 389, then repeat: 3890 / 600

Advancing to step 8:
3890 divided by 600 is 6 with a remainder of 290.
Put 6 as the next digit of the answer. 
Result so far: 118576.0
If we take 3600 away from 3890, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 9:
600 goes into 2900 4 times with a remainder of 500.
The next digit of our result is 4. 
Result so far: 118576.4
If we take 2400 away from 2900, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 10:
When dividing 5000 by 600, we get 8 with a remainder of 200.
Record the quotient 8 as the next digit in the result. 
Result so far: 118576.48
Deduct 4800 from 5000 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
If we divide 2000 by 600, we get 3 and a remainder of 200.
Record the quotient 3 as the next digit in the result. 
Result so far: 118576.483
Subtracting 1800 from 2000 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
The number 600 fits into 2000 3 times, leaving a remainder of 200.
Record the quotient 3 as the next digit in the result. 
Result so far: 118576.4833
The remainder is 200 after subtracting 1800 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 118576.4833 and a remainder of 0.002.
