77863811 divided by 600 
The aim is to understand the frequency of 600 in 77863811.

On to step 1:
600 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 600

Moving on to step 2:
600 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 600

Moving on to step 3:
If we divide 778 by 600, we get 1 and a remainder of 178.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 600 away from 778, we end up with 178.
Bring next digit (6) of the dividend behind the 178 and repeat the process: 1786 / 600

Moving on to step 4:
If we divide 1786 by 600, we get 2 and a remainder of 586.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 1200 from 1786 to get 586.
Fetch the next digit (3) from the dividend, attach it to 586 and continue: 5863 / 600

Step 5:
When dividing 5863 by 600, we get 9 with a remainder of 463.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Deduct 5400 from 5863 and we're left with 463.
Grab the next digit (8) from the dividend, add it to 463, then carry on: 4638 / 600

Let's proceed to step 6:
4638 divided by 600 is 7 with a remainder of 438.
The number 7 becomes the next digit in our result. 
Result so far: 1297.0
If we subtract 4200 from 4638, we get 438.
Take the next digit (1) from the dividend and append it to 438, then repeat: 4381 / 600

Let's proceed to step 7:
When dividing 4381 by 600, we get 7 with a remainder of 181.
Write down 7 as next digit of the result. 
Result so far: 12977.0
The remainder is 181 after subtracting 4200 from 4381.
Grab the next digit (1) from the dividend, add it to 181, then carry on: 1811 / 600

Going ahead to step 8:
1811 divided by 600 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 129773.0
Deduct 1800 from 1811 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
When dividing 110 by 600, we get 0 with a remainder of 110.
The next digit of our result is 0. 
Result so far: 129773.0
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
600 can be fit into 1100 1 times, resulting in a remainder of 500.
Use 1 as the next digit of our solution. 
Result so far: 129773.01
Deduct 600 from 1100 and we're left 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.

Moving on to step 11:
When dividing 5000 by 600, we get 8 with a remainder of 200.
Use 8 as the next digit of our solution. 
Result so far: 129773.018
If we subtract 4800 from 5000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
When dividing 2000 by 600, we get 3 with a remainder of 200.
Use 3 as the next digit of our solution. 
Result so far: 129773.0183
If we subtract 1800 from 2000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 13:
2000 divided by 600 is 3 with a remainder of 200.
Use 3 as the next digit of our solution. 
Result so far: 129773.01833
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.

The final result is 129773.01833 with a remainder of 0.0002.
