We look at the division of 51130336 by 902 
The aim is to understand the frequency of 902 in 51130336.

Step 1:
902 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 902

Moving on to step 2:
When dividing 51 by 902, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 902

Advancing to step 3:
511 divided by 902 is 0 with a remainder of 511.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 511 leaves us with 511.
Bring next digit (3) of the dividend behind the 511 and repeat the process: 5113 / 902

Going ahead to step 4:
5113 divided by 902 is 5 with a remainder of 603.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 4510 from 5113 and we're left with 603.
Append the next digit (0) from the dividend to 603 and continue with: 6030 / 902

Step 5:
The number 902 fits into 6030 6 times, leaving a remainder of 618.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtracting 5412 from 6030 leaves us with 618.
Include the next digit (3) from the dividend after 618, then repeat: 6183 / 902

Going ahead to step 6:
6183 divided by 902 is 6 with a remainder of 771.
Use 6 as the next digit of our solution. 
Result so far: 566.0
Deduct 5412 from 6183 and we're left with 771.
Fetch the next digit (3) from the dividend, attach it to 771 and continue: 7713 / 902

Going ahead to step 7:
When dividing 7713 by 902, we get 8 with a remainder of 497.
Write down 8 as next digit of the result. 
Result so far: 5668.0
Subtract 7216 from 7713 to get 497.
Fetch the next digit (6) from the dividend, attach it to 497 and continue: 4976 / 902

Step 8:
902 can be fit into 4976 5 times, resulting in a remainder of 466.
The next digit of our result is 5. 
Result so far: 56685.0
Subtracting 4510 from 4976 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Step 9:
902 can be fit into 4660 5 times, resulting in a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 56685.5
Subtracting 4510 from 4660 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
When dividing 1500 by 902, we get 1 with a remainder of 598.
The number 1 becomes the next digit in our result. 
Result so far: 56685.51
The remainder is 598 after subtracting 902 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Going ahead to step 11:
The number 902 fits into 5980 6 times, leaving a remainder of 568.
Record the quotient 6 as the next digit in the result. 
Result so far: 56685.516
Deduct 5412 from 5980 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Going ahead to step 12:
The number 902 fits into 5680 6 times, leaving a remainder of 268.
Record the quotient 6 as the next digit in the result. 
Result so far: 56685.5166
If we subtract 5412 from 5680, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final outcome is 56685.5166, with a leftover of 0.00268.
