Let's divide 23889406 by 902
The aim is to understand the frequency of 902 in 23889406.

On to step 1:
902 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 902

Advancing to step 2:
902 goes into 23 0 times with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 902

On to step 3:
902 goes into 238 0 times with a remainder of 238.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 238, we end up with 238.
Append the next digit (8) from the dividend to 238 and continue with: 2388 / 902

Step 4:
902 goes into 2388 2 times with a remainder of 584.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1804 away from 2388, we end up with 584.
Fetch the next digit (9) from the dividend, attach it to 584 and continue: 5849 / 902

Moving on to step 5:
5849 divided by 902 is 6 with a remainder of 437.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtract 5412 from 5849 to get 437.
Bring next digit (4) of the dividend behind the 437 and repeat the process: 4374 / 902

On to step 6:
4374 divided by 902 is 4 with a remainder of 766.
Put 4 as the next digit of the answer. 
Result so far: 264.0
Deduct 3608 from 4374 and we're left with 766.
Grab the next digit (0) from the dividend, add it to 766, then carry on: 7660 / 902

Step 7:
The number 902 fits into 7660 8 times, leaving a remainder of 444.
Put 8 as the next digit of the answer. 
Result so far: 2648.0
Deduct 7216 from 7660 and we're left with 444.
Append the next digit (6) from the dividend to 444 and continue with: 4446 / 902

Advancing to step 8:
When dividing 4446 by 902, we get 4 with a remainder of 838.
Put 4 as the next digit of the answer. 
Result so far: 26484.0
Subtract 3608 from 4446 to get 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

On to step 9:
902 can be fit into 8380 9 times, resulting in a remainder of 262.
The next digit of our result is 9. 
Result so far: 26484.9
If we subtract 8118 from 8380, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 10:
If we divide 2620 by 902, we get 2 and a remainder of 816.
Write down 2 as next digit of the result. 
Result so far: 26484.92
If we take 1804 away from 2620, we end up with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Moving on to step 11:
8160 divided by 902 is 9 with a remainder of 42.
The next digit of our result is 9. 
Result so far: 26484.929
Subtract 8118 from 8160 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
If we divide 420 by 902, we get 0 and a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 26484.929
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 13:
When dividing 4200 by 902, we get 4 with a remainder of 592.
Write down 4 as next digit of the result. 
Result so far: 26484.92904
The remainder is 592 after subtracting 3608 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Moving on to step 14:
902 goes into 5920 6 times with a remainder of 508.
Put 6 as the next digit of the answer. 
Result so far: 26484.929046
Subtracting 5412 from 5920 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 15:
The number 902 fits into 5080 5 times, leaving a remainder of 570.
The number 5 becomes the next digit in our result. 
Result so far: 26484.9290465
Deduct 4510 from 5080 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 16:
5700 divided by 902 is 6 with a remainder of 288.
The next digit of our result is 6. 
Result so far: 26484.92904656
If we take 5412 away from 5700, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final result is 26484.92904656 with a remainder of 2.88e-07.
