Let's divide 63999030 by 902
The aim is to understand the frequency of 902 in 63999030.

Let's proceed to step 1:
902 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 902

Going ahead to step 2:
If we divide 63 by 902, we get 0 and a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 902

Advancing to step 3:
When dividing 639 by 902, we get 0 with a remainder of 639.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 639 and we're left with 639.
Grab the next digit (9) from the dividend, add it to 639, then carry on: 6399 / 902

Step 4:
6399 divided by 902 is 7 with a remainder of 85.
The next digit of our result is 7. 
Result so far: 7.0
If we take 6314 away from 6399, we end up with 85.
Bring next digit (9) of the dividend behind the 85 and repeat the process: 859 / 902

Step 5:
902 goes into 859 0 times with a remainder of 859.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Deduct 0 from 859 and we're left with 859.
Include the next digit (0) from the dividend after 859, then repeat: 8590 / 902

On to step 6:
902 can be fit into 8590 9 times, resulting in a remainder of 472.
Write down 9 as next digit of the result. 
Result so far: 709.0
Deduct 8118 from 8590 and we're left with 472.
Bring next digit (3) of the dividend behind the 472 and repeat the process: 4723 / 902

Let's proceed to step 7:
4723 divided by 902 is 5 with a remainder of 213.
Record the quotient 5 as the next digit in the result. 
Result so far: 7095.0
If we take 4510 away from 4723, we end up with 213.
Fetch the next digit (0) from the dividend, attach it to 213 and continue: 2130 / 902

Step 8:
902 goes into 2130 2 times with a remainder of 326.
Use 2 as the next digit of our solution. 
Result so far: 70952.0
The remainder is 326 after subtracting 1804 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 9:
If we divide 3260 by 902, we get 3 and a remainder of 554.
Use 3 as the next digit of our solution. 
Result so far: 70952.3
The remainder is 554 after subtracting 2706 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Going ahead to step 10:
902 goes into 5540 6 times with a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 70952.36
If we take 5412 away from 5540, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 11:
902 goes into 1280 1 times with a remainder of 378.
Record the quotient 1 as the next digit in the result. 
Result so far: 70952.361
Subtract 902 from 1280 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Going ahead to step 12:
The number 902 fits into 3780 4 times, leaving a remainder of 172.
The next digit of our result is 4. 
Result so far: 70952.3614
Subtract 3608 from 3780 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 13:
902 goes into 1720 1 times with a remainder of 818.
Put 1 as the next digit of the answer. 
Result so far: 70952.36141
If we take 902 away from 1720, we end up with 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

Let's proceed to step 14:
8180 divided by 902 is 9 with a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 70952.361419
Deduct 8118 from 8180 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 15:
902 can be fit into 620 0 times, resulting in a remainder of 620.
Write down 0 as next digit of the result. 
Result so far: 70952.361419
If we subtract 0 from 620, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 16:
When dividing 6200 by 902, we get 6 with a remainder of 788.
Record the quotient 6 as the next digit in the result. 
Result so far: 70952.36141906
If we subtract 5412 from 6200, we get 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

The final result is 70952.36141906 with a remainder of 7.88e-07.
