We look at the division of 57294771 by 800 
The aim is to understand the frequency of 800 in 57294771.

On to step 1:
800 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 800

Going ahead to step 2:
800 goes into 57 0 times with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Grab the next digit (2) from the dividend, add it to 57, then carry on: 572 / 800

On to step 3:
When dividing 572 by 800, we get 0 with a remainder of 572.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 572 and we're left with 572.
Fetch the next digit (9) from the dividend, attach it to 572 and continue: 5729 / 800

On to step 4:
When dividing 5729 by 800, we get 7 with a remainder of 129.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 5600 from 5729 to get 129.
Grab the next digit (4) from the dividend, add it to 129, then carry on: 1294 / 800

Step 5:
1294 divided by 800 is 1 with a remainder of 494.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtract 800 from 1294 to get 494.
Bring next digit (7) of the dividend behind the 494 and repeat the process: 4947 / 800

On to step 6:
If we divide 4947 by 800, we get 6 and a remainder of 147.
Use 6 as the next digit of our solution. 
Result so far: 716.0
Deduct 4800 from 4947 and we're left with 147.
Take the next digit (7) from the dividend and append it to 147, then repeat: 1477 / 800

Advancing to step 7:
800 can be fit into 1477 1 times, resulting in a remainder of 677.
Write down 1 as next digit of the result. 
Result so far: 7161.0
The remainder is 677 after subtracting 800 from 1477.
Grab the next digit (1) from the dividend, add it to 677, then carry on: 6771 / 800

Advancing to step 8:
6771 divided by 800 is 8 with a remainder of 371.
The next digit of our result is 8. 
Result so far: 71618.0
Subtract 6400 from 6771 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Going ahead to step 9:
3710 divided by 800 is 4 with a remainder of 510.
The number 4 becomes the next digit in our result. 
Result so far: 71618.4
The remainder is 510 after subtracting 3200 from 3710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 10:
If we divide 5100 by 800, we get 6 and a remainder of 300.
Write down 6 as next digit of the result. 
Result so far: 71618.46
If we take 4800 away from 5100, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 11:
If we divide 3000 by 800, we get 3 and a remainder of 600.
The number 3 becomes the next digit in our result. 
Result so far: 71618.463
If we subtract 2400 from 3000, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 12:
The number 800 fits into 6000 7 times, leaving a remainder of 400.
The number 7 becomes the next digit in our result. 
Result so far: 71618.4637
If we take 5600 away from 6000, 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.

Moving on to step 13:
If we divide 4000 by 800, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 71618.46375
If we take 4000 away from 4000, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 14:
800 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 71618.46375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
When dividing 0 by 800, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 71618.46375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 71618.46375, and the remainder is 0.0.
