We're dividing 73199795 by 902 
The aim is to understand the frequency of 902 in 73199795.

Advancing to step 1:
If we divide 7 by 902, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 902

Step 2:
The number 902 fits into 73 0 times, leaving a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 902

Going ahead to step 3:
902 can be fit into 731 0 times, resulting in a remainder of 731.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 731, we get 731.
Append the next digit (9) from the dividend to 731 and continue with: 7319 / 902

Going ahead to step 4:
7319 divided by 902 is 8 with a remainder of 103.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 7216 from 7319 and we're left with 103.
Grab the next digit (9) from the dividend, add it to 103, then carry on: 1039 / 902

Advancing to step 5:
1039 divided by 902 is 1 with a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtract 902 from 1039 to get 137.
Grab the next digit (7) from the dividend, add it to 137, then carry on: 1377 / 902

Moving on to step 6:
902 goes into 1377 1 times with a remainder of 475.
Record the quotient 1 as the next digit in the result. 
Result so far: 811.0
Subtracting 902 from 1377 leaves us with 475.
Bring next digit (9) of the dividend behind the 475 and repeat the process: 4759 / 902

Moving on to step 7:
902 goes into 4759 5 times with a remainder of 249.
Put 5 as the next digit of the answer. 
Result so far: 8115.0
Subtract 4510 from 4759 to get 249.
Append the next digit (5) from the dividend to 249 and continue with: 2495 / 902

On to step 8:
If we divide 2495 by 902, we get 2 and a remainder of 691.
The number 2 becomes the next digit in our result. 
Result so far: 81152.0
If we subtract 1804 from 2495, we get 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

On to step 9:
902 goes into 6910 7 times with a remainder of 596.
Use 7 as the next digit of our solution. 
Result so far: 81152.7
If we take 6314 away from 6910, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Going ahead to step 10:
When dividing 5960 by 902, we get 6 with a remainder of 548.
Record the quotient 6 as the next digit in the result. 
Result so far: 81152.76
Deduct 5412 from 5960 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

On to step 11:
If we divide 5480 by 902, we get 6 and a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 81152.766
Deduct 5412 from 5480 and we're left 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.

After the division, we end up with 81152.766 and a remainder of 0.0068.
