We look at the division of 63723381 by 902 
The aim is to understand the frequency of 902 in 63723381.

Moving on to step 1:
902 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 902

Moving on to step 2:
The number 902 fits into 63 0 times, leaving a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 902

Advancing to step 3:
637 divided by 902 is 0 with a remainder of 637.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 637 leaves us with 637.
Include the next digit (2) from the dividend after 637, then repeat: 6372 / 902

Moving on to step 4:
When dividing 6372 by 902, we get 7 with a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 6314 away from 6372, we end up with 58.
Take the next digit (3) from the dividend and append it to 58, then repeat: 583 / 902

On to step 5:
The number 902 fits into 583 0 times, leaving a remainder of 583.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Deduct 0 from 583 and we're left with 583.
Append the next digit (3) from the dividend to 583 and continue with: 5833 / 902

Step 6:
5833 divided by 902 is 6 with a remainder of 421.
Use 6 as the next digit of our solution. 
Result so far: 706.0
Subtract 5412 from 5833 to get 421.
Include the next digit (8) from the dividend after 421, then repeat: 4218 / 902

Advancing to step 7:
If we divide 4218 by 902, we get 4 and a remainder of 610.
Put 4 as the next digit of the answer. 
Result so far: 7064.0
If we subtract 3608 from 4218, we get 610.
Fetch the next digit (1) from the dividend, attach it to 610 and continue: 6101 / 902

Going ahead to step 8:
6101 divided by 902 is 6 with a remainder of 689.
Write down 6 as next digit of the result. 
Result so far: 70646.0
If we subtract 5412 from 6101, we get 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Step 9:
When dividing 6890 by 902, we get 7 with a remainder of 576.
The next digit of our result is 7. 
Result so far: 70646.7
Subtracting 6314 from 6890 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 10:
If we divide 5760 by 902, we get 6 and a remainder of 348.
Record the quotient 6 as the next digit in the result. 
Result so far: 70646.76
Subtracting 5412 from 5760 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 11:
902 goes into 3480 3 times with a remainder of 774.
Record the quotient 3 as the next digit in the result. 
Result so far: 70646.763
The remainder is 774 after subtracting 2706 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Advancing to step 12:
7740 divided by 902 is 8 with a remainder of 524.
The number 8 becomes the next digit in our result. 
Result so far: 70646.7638
Subtracting 7216 from 7740 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 13:
5240 divided by 902 is 5 with a remainder of 730.
Write down 5 as next digit of the result. 
Result so far: 70646.76385
The remainder is 730 after subtracting 4510 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Advancing to step 14:
902 can be fit into 7300 8 times, resulting in a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 70646.763858
The remainder is 84 after subtracting 7216 from 7300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 15:
840 divided by 902 is 0 with a remainder of 840.
Record the quotient 0 as the next digit in the result. 
Result so far: 70646.763858
Deduct 0 from 840 and we're left with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Moving on to step 16:
902 goes into 8400 9 times with a remainder of 282.
Record the quotient 9 as the next digit in the result. 
Result so far: 70646.76385809
The remainder is 282 after subtracting 8118 from 8400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

The quotient of the division is 70646.76385809, and the remainder is 2.82e-07.
