52738181 divided by 902 
The aim is to understand the frequency of 902 in 52738181.

Advancing to step 1:
5 divided by 902 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 902

On to step 2:
The number 902 fits into 52 0 times, leaving a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Bring next digit (7) of the dividend behind the 52 and repeat the process: 527 / 902

Going ahead to step 3:
If we divide 527 by 902, we get 0 and a remainder of 527.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 527 after subtracting 0 from 527.
Fetch the next digit (3) from the dividend, attach it to 527 and continue: 5273 / 902

On to step 4:
902 can be fit into 5273 5 times, resulting in a remainder of 763.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 4510 away from 5273, we end up with 763.
Grab the next digit (8) from the dividend, add it to 763, then carry on: 7638 / 902

Step 5:
902 goes into 7638 8 times with a remainder of 422.
Use 8 as the next digit of our solution. 
Result so far: 58.0
The remainder is 422 after subtracting 7216 from 7638.
Take the next digit (1) from the dividend and append it to 422, then repeat: 4221 / 902

On to step 6:
902 goes into 4221 4 times with a remainder of 613.
The number 4 becomes the next digit in our result. 
Result so far: 584.0
Subtract 3608 from 4221 to get 613.
Include the next digit (8) from the dividend after 613, then repeat: 6138 / 902

Going ahead to step 7:
902 can be fit into 6138 6 times, resulting in a remainder of 726.
Record the quotient 6 as the next digit in the result. 
Result so far: 5846.0
Subtracting 5412 from 6138 leaves us with 726.
Take the next digit (1) from the dividend and append it to 726, then repeat: 7261 / 902

On to step 8:
902 goes into 7261 8 times with a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 58468.0
Subtract 7216 from 7261 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
The number 902 fits into 450 0 times, leaving a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 58468.0
If we take 0 away from 450, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 10:
The number 902 fits into 4500 4 times, leaving a remainder of 892.
The number 4 becomes the next digit in our result. 
Result so far: 58468.04
Subtracting 3608 from 4500 leaves us with 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

On to step 11:
8920 divided by 902 is 9 with a remainder of 802.
Put 9 as the next digit of the answer. 
Result so far: 58468.049
If we subtract 8118 from 8920, we get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

On to step 12:
8020 divided by 902 is 8 with a remainder of 804.
The next digit of our result is 8. 
Result so far: 58468.0498
Subtract 7216 from 8020 to get 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Advancing to step 13:
902 goes into 8040 8 times with a remainder of 824.
The number 8 becomes the next digit in our result. 
Result so far: 58468.04988
If we take 7216 away from 8040, we end up with 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

After the division, we end up with 58468.04988 and a remainder of 0.000824.
