We're dividing 77639116 by 702 
The aim is to understand the frequency of 702 in 77639116.

Moving on to step 1:
When dividing 7 by 702, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 702

Advancing to step 2:
77 divided by 702 is 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 702

Let's proceed to step 3:
776 divided by 702 is 1 with a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 74 after subtracting 702 from 776.
Take the next digit (3) from the dividend and append it to 74, then repeat: 743 / 702

On to step 4:
743 divided by 702 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 702 from 743 leaves us with 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 702

On to step 5:
702 can be fit into 419 0 times, resulting in a remainder of 419.
Write down 0 as next digit of the result. 
Result so far: 110.0
The remainder is 419 after subtracting 0 from 419.
Grab the next digit (1) from the dividend, add it to 419, then carry on: 4191 / 702

Moving on to step 6:
702 goes into 4191 5 times with a remainder of 681.
The next digit of our result is 5. 
Result so far: 1105.0
If we take 3510 away from 4191, we end up with 681.
Append the next digit (1) from the dividend to 681 and continue with: 6811 / 702

Step 7:
If we divide 6811 by 702, we get 9 and a remainder of 493.
The next digit of our result is 9. 
Result so far: 11059.0
If we subtract 6318 from 6811, we get 493.
Bring next digit (6) of the dividend behind the 493 and repeat the process: 4936 / 702

Step 8:
4936 divided by 702 is 7 with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 110597.0
The remainder is 22 after subtracting 4914 from 4936.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
220 divided by 702 is 0 with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 110597.0
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
When dividing 2200 by 702, we get 3 with a remainder of 94.
The number 3 becomes the next digit in our result. 
Result so far: 110597.03
If we take 2106 away from 2200, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 11:
702 can be fit into 940 1 times, resulting in a remainder of 238.
Write down 1 as next digit of the result. 
Result so far: 110597.031
The remainder is 238 after subtracting 702 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 12:
When dividing 2380 by 702, we get 3 with a remainder of 274.
Use 3 as the next digit of our solution. 
Result so far: 110597.0313
The remainder is 274 after subtracting 2106 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 13:
The number 702 fits into 2740 3 times, leaving a remainder of 634.
The next digit of our result is 3. 
Result so far: 110597.03133
If we subtract 2106 from 2740, we get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

The final result is 110597.03133 with a remainder of 0.000634.
