We're dividing 53748760 by 902 
The aim is to understand the frequency of 902 in 53748760.

Going ahead to step 1:
When dividing 5 by 902, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 902

Step 2:
The number 902 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 902

Moving on to step 3:
902 goes into 537 0 times with a remainder of 537.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 537 after subtracting 0 from 537.
Include the next digit (4) from the dividend after 537, then repeat: 5374 / 902

Advancing to step 4:
When dividing 5374 by 902, we get 5 with a remainder of 864.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 4510 from 5374, we get 864.
Grab the next digit (8) from the dividend, add it to 864, then carry on: 8648 / 902

Advancing to step 5:
8648 divided by 902 is 9 with a remainder of 530.
Put 9 as the next digit of the answer. 
Result so far: 59.0
Deduct 8118 from 8648 and we're left with 530.
Grab the next digit (7) from the dividend, add it to 530, then carry on: 5307 / 902

Moving on to step 6:
902 can be fit into 5307 5 times, resulting in a remainder of 797.
The next digit of our result is 5. 
Result so far: 595.0
If we subtract 4510 from 5307, we get 797.
Bring next digit (6) of the dividend behind the 797 and repeat the process: 7976 / 902

Let's proceed to step 7:
902 goes into 7976 8 times with a remainder of 760.
Use 8 as the next digit of our solution. 
Result so far: 5958.0
Subtracting 7216 from 7976 leaves us with 760.
Include the next digit (0) from the dividend after 760, then repeat: 7600 / 902

Going ahead to step 8:
When dividing 7600 by 902, we get 8 with a remainder of 384.
The next digit of our result is 8. 
Result so far: 59588.0
If we subtract 7216 from 7600, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 9:
When dividing 3840 by 902, we get 4 with a remainder of 232.
The next digit of our result is 4. 
Result so far: 59588.4
Subtracting 3608 from 3840 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 10:
When dividing 2320 by 902, we get 2 with a remainder of 516.
The number 2 becomes the next digit in our result. 
Result so far: 59588.42
If we take 1804 away from 2320, we end up with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

On to step 11:
5160 divided by 902 is 5 with a remainder of 650.
The next digit of our result is 5. 
Result so far: 59588.425
The remainder is 650 after subtracting 4510 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 12:
If we divide 6500 by 902, we get 7 and a remainder of 186.
Write down 7 as next digit of the result. 
Result so far: 59588.4257
Deduct 6314 from 6500 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 13:
1860 divided by 902 is 2 with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 59588.42572
If we take 1804 away from 1860, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
When dividing 560 by 902, we get 0 with a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 59588.42572
If we subtract 0 from 560, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 15:
The number 902 fits into 5600 6 times, leaving a remainder of 188.
The next digit of our result is 6. 
Result so far: 59588.4257206
Deduct 5412 from 5600 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 16:
902 goes into 1880 2 times with a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 59588.42572062
Subtract 1804 from 1880 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 59588.42572062, with a leftover of 7.6e-08.
