65420910 divided by 902 
The aim is to understand the frequency of 902 in 65420910.

Going ahead to step 1:
When dividing 6 by 902, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 902

Step 2:
902 goes into 65 0 times with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 902

Advancing to step 3:
When dividing 654 by 902, we get 0 with a remainder of 654.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 654 and we're left with 654.
Fetch the next digit (2) from the dividend, attach it to 654 and continue: 6542 / 902

Advancing to step 4:
6542 divided by 902 is 7 with a remainder of 228.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 6314 from 6542 and we're left with 228.
Bring next digit (0) of the dividend behind the 228 and repeat the process: 2280 / 902

Advancing to step 5:
If we divide 2280 by 902, we get 2 and a remainder of 476.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 476 after subtracting 1804 from 2280.
Include the next digit (9) from the dividend after 476, then repeat: 4769 / 902

Advancing to step 6:
902 can be fit into 4769 5 times, resulting in a remainder of 259.
The number 5 becomes the next digit in our result. 
Result so far: 725.0
If we take 4510 away from 4769, we end up with 259.
Grab the next digit (1) from the dividend, add it to 259, then carry on: 2591 / 902

Let's proceed to step 7:
If we divide 2591 by 902, we get 2 and a remainder of 787.
Record the quotient 2 as the next digit in the result. 
Result so far: 7252.0
If we subtract 1804 from 2591, we get 787.
Bring next digit (0) of the dividend behind the 787 and repeat the process: 7870 / 902

Step 8:
7870 divided by 902 is 8 with a remainder of 654.
Put 8 as the next digit of the answer. 
Result so far: 72528.0
The remainder is 654 after subtracting 7216 from 7870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Step 9:
6540 divided by 902 is 7 with a remainder of 226.
Put 7 as the next digit of the answer. 
Result so far: 72528.7
Deduct 6314 from 6540 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 10:
When dividing 2260 by 902, we get 2 with a remainder of 456.
Write down 2 as next digit of the result. 
Result so far: 72528.72
Deduct 1804 from 2260 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 11:
When dividing 4560 by 902, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 72528.725
The remainder is 50 after subtracting 4510 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
The number 902 fits into 500 0 times, leaving a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 72528.725
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 13:
When dividing 5000 by 902, we get 5 with a remainder of 490.
The number 5 becomes the next digit in our result. 
Result so far: 72528.72505
Deduct 4510 from 5000 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 14:
If we divide 4900 by 902, we get 5 and a remainder of 390.
The next digit of our result is 5. 
Result so far: 72528.725055
The remainder is 390 after subtracting 4510 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The final result is 72528.725055 with a remainder of 3.9e-05.
