669953 divided by 77 
The aim is to understand the frequency of 77 in 669953.

Moving on to step 1:
If we divide 6 by 77, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 77

Going ahead to step 2:
77 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 77

Let's proceed to step 3:
When dividing 669 by 77, we get 8 with a remainder of 53.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 616 away from 669, we end up with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 77

Moving on to step 4:
When dividing 539 by 77, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we subtract 539 from 539, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 77

Moving on to step 5:
The number 77 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 870.0
Subtract 0 from 5 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 77

Let's proceed to step 6:
77 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 8700.0
Deduct 0 from 53 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
77 goes into 530 6 times with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 8700.6
If we take 462 away from 530, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 8:
The number 77 fits into 680 8 times, leaving a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 8700.68
Deduct 616 from 680 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
If we divide 640 by 77, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 8700.688
Subtract 616 from 640 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 8700.688 with a balance of 0.0024.
