We're dividing 78677046 by 902 
The aim is to understand the frequency of 902 in 78677046.

On to step 1:
If we divide 7 by 902, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 902

On to step 2:
The number 902 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 902

Going ahead to step 3:
When dividing 786 by 902, we get 0 with a remainder of 786.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 786, we end up with 786.
Append the next digit (7) from the dividend to 786 and continue with: 7867 / 902

Let's proceed to step 4:
The number 902 fits into 7867 8 times, leaving a remainder of 651.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 7216 from 7867 to get 651.
Append the next digit (7) from the dividend to 651 and continue with: 6517 / 902

Let's proceed to step 5:
6517 divided by 902 is 7 with a remainder of 203.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we subtract 6314 from 6517, we get 203.
Take the next digit (0) from the dividend and append it to 203, then repeat: 2030 / 902

Step 6:
902 goes into 2030 2 times with a remainder of 226.
Record the quotient 2 as the next digit in the result. 
Result so far: 872.0
Subtracting 1804 from 2030 leaves us with 226.
Take the next digit (4) from the dividend and append it to 226, then repeat: 2264 / 902

Let's proceed to step 7:
902 can be fit into 2264 2 times, resulting in a remainder of 460.
The next digit of our result is 2. 
Result so far: 8722.0
If we take 1804 away from 2264, we end up with 460.
Take the next digit (6) from the dividend and append it to 460, then repeat: 4606 / 902

Advancing to step 8:
902 goes into 4606 5 times with a remainder of 96.
Put 5 as the next digit of the answer. 
Result so far: 87225.0
Subtract 4510 from 4606 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 9:
960 divided by 902 is 1 with a remainder of 58.
The next digit of our result is 1. 
Result so far: 87225.1
Subtracting 902 from 960 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
902 goes into 580 0 times with a remainder of 580.
The number 0 becomes the next digit in our result. 
Result so far: 87225.1
If we take 0 away from 580, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 11:
5800 divided by 902 is 6 with a remainder of 388.
Put 6 as the next digit of the answer. 
Result so far: 87225.106
Deduct 5412 from 5800 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 12:
The number 902 fits into 3880 4 times, leaving a remainder of 272.
Put 4 as the next digit of the answer. 
Result so far: 87225.1064
If we subtract 3608 from 3880, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 13:
2720 divided by 902 is 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 87225.10643
Subtract 2706 from 2720 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
The number 902 fits into 140 0 times, leaving a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 87225.10643
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 15:
If we divide 1400 by 902, we get 1 and a remainder of 498.
Record the quotient 1 as the next digit in the result. 
Result so far: 87225.1064301
If we subtract 902 from 1400, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Step 16:
If we divide 4980 by 902, we get 5 and a remainder of 470.
The number 5 becomes the next digit in our result. 
Result so far: 87225.10643015
If we subtract 4510 from 4980, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Our division results in 87225.10643015 with a remaining 4.7e-07.
