We look at the division of 403656 by 77 
The aim is to understand the frequency of 77 in 403656.

Let's proceed to step 1:
77 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 77

On to step 2:
When dividing 40 by 77, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 77

Let's proceed to step 3:
77 can be fit into 403 5 times, resulting in a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 385 away from 403, we end up with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 77

Advancing to step 4:
If we divide 186 by 77, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtract 154 from 186 to get 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 77

Advancing to step 5:
The number 77 fits into 325 4 times, leaving a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 524.0
If we take 308 away from 325, we end up with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 77

Advancing to step 6:
If we divide 176 by 77, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 5242.0
If we take 154 away from 176, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
220 divided by 77 is 2 with a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 5242.2
Subtract 154 from 220 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
660 divided by 77 is 8 with a remainder of 44.
The next digit of our result is 8. 
Result so far: 5242.28
If we subtract 616 from 660, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
77 goes into 440 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 5242.285
If we subtract 385 from 440, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
The number 77 fits into 550 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 5242.2857
Deduct 539 from 550 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
110 divided by 77 is 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 5242.28571
Deduct 77 from 110 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 12:
The number 77 fits into 330 4 times, leaving a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 5242.285714
If we take 308 away from 330, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
220 divided by 77 is 2 with a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 5242.2857142
If we subtract 154 from 220, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 14:
The number 77 fits into 660 8 times, leaving a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 5242.28571428
Deduct 616 from 660 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 5242.28571428, and the remainder is 4.4e-08.
