We divide 637741 by 80
The aim is to understand the frequency of 80 in 637741.

Advancing to step 1:
The number 80 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 80

Let's proceed to step 2:
When dividing 63 by 80, we get 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 80

On to step 3:
637 divided by 80 is 7 with a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 560 away from 637, we end up with 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 80

On to step 4:
The number 80 fits into 777 9 times, leaving a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Deduct 720 from 777 and we're left with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 80

Advancing to step 5:
If we divide 574 by 80, we get 7 and a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 797.0
Subtract 560 from 574 to get 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 80

Let's proceed to step 6:
80 goes into 141 1 times with a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 7971.0
Subtract 80 from 141 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 7:
When dividing 610 by 80, we get 7 with a remainder of 50.
The next digit of our result is 7. 
Result so far: 7971.7
Subtracting 560 from 610 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
The number 80 fits into 500 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 7971.76
If we subtract 480 from 500, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 7971.762
Subtract 160 from 200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
80 goes into 400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 7971.7625
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7971.7625
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 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7971.7625
If we subtract 0 from 0, we get 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 7971.7625 with a remaining 0.0.
