We divide 370899 by 77
The aim is to understand the frequency of 77 in 370899.

Step 1:
If we divide 3 by 77, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 77

Let's proceed to step 2:
When dividing 37 by 77, we get 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 77

On to step 3:
The number 77 fits into 370 4 times, leaving a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 62 after subtracting 308 from 370.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 77

Let's proceed to step 4:
77 can be fit into 628 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we subtract 616 from 628, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 77

On to step 5:
77 goes into 129 1 times with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 481.0
Deduct 77 from 129 and we're left with 52.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 77

Moving on to step 6:
When dividing 529 by 77, we get 6 with a remainder of 67.
Put 6 as the next digit of the answer. 
Result so far: 4816.0
Deduct 462 from 529 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 7:
670 divided by 77 is 8 with a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 4816.8
The remainder is 54 after subtracting 616 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
When dividing 540 by 77, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 4816.87
Subtract 539 from 540 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
The number 77 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 4816.87
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
100 divided by 77 is 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 4816.8701
Subtracting 77 from 100 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
When dividing 230 by 77, we get 2 with a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 4816.87012
Subtracting 154 from 230 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 12:
The number 77 fits into 760 9 times, leaving a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 4816.870129
The remainder is 67 after subtracting 693 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 13:
When dividing 670 by 77, we get 8 with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 4816.8701298
Subtract 616 from 670 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 14:
77 goes into 540 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 4816.87012987
Subtract 539 from 540 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 4816.87012987, and the remainder is 1e-09.
