We look at the division of 76377729 by 800 
The aim is to understand the frequency of 800 in 76377729.

Let's proceed to step 1:
800 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 800

Advancing to step 2:
76 divided by 800 is 0 with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Append the next digit (3) from the dividend to 76 and continue with: 763 / 800

Going ahead to step 3:
The number 800 fits into 763 0 times, leaving a remainder of 763.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 763, we get 763.
Grab the next digit (7) from the dividend, add it to 763, then carry on: 7637 / 800

Let's proceed to step 4:
The number 800 fits into 7637 9 times, leaving a remainder of 437.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7200 from 7637, we get 437.
Grab the next digit (7) from the dividend, add it to 437, then carry on: 4377 / 800

Step 5:
4377 divided by 800 is 5 with a remainder of 377.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Deduct 4000 from 4377 and we're left with 377.
Append the next digit (7) from the dividend to 377 and continue with: 3777 / 800

Going ahead to step 6:
800 can be fit into 3777 4 times, resulting in a remainder of 577.
Use 4 as the next digit of our solution. 
Result so far: 954.0
The remainder is 577 after subtracting 3200 from 3777.
Fetch the next digit (2) from the dividend, attach it to 577 and continue: 5772 / 800

Step 7:
800 goes into 5772 7 times with a remainder of 172.
The next digit of our result is 7. 
Result so far: 9547.0
The remainder is 172 after subtracting 5600 from 5772.
Include the next digit (9) from the dividend after 172, then repeat: 1729 / 800

Advancing to step 8:
If we divide 1729 by 800, we get 2 and a remainder of 129.
The number 2 becomes the next digit in our result. 
Result so far: 95472.0
The remainder is 129 after subtracting 1600 from 1729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 9:
800 goes into 1290 1 times with a remainder of 490.
The next digit of our result is 1. 
Result so far: 95472.1
Deduct 800 from 1290 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 10:
4900 divided by 800 is 6 with a remainder of 100.
Put 6 as the next digit of the answer. 
Result so far: 95472.16
Deduct 4800 from 4900 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 11:
The number 800 fits into 1000 1 times, leaving a remainder of 200.
Record the quotient 1 as the next digit in the result. 
Result so far: 95472.161
Deduct 800 from 1000 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.

Going ahead to step 12:
When dividing 2000 by 800, we get 2 with a remainder of 400.
Record the quotient 2 as the next digit in the result. 
Result so far: 95472.1612
The remainder is 400 after subtracting 1600 from 2000.
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:
4000 divided by 800 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 95472.16125
Subtracting 4000 from 4000 leaves us 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.

Advancing to step 14:
When dividing 0 by 800, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 95472.16125
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.

Advancing to step 15:
800 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 95472.16125
Subtracting 0 from 0 leaves us 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.

Our division results in 95472.16125 with a remaining 0.0.
