We look at the division of 72411502 by 902 
The aim is to understand the frequency of 902 in 72411502.

Moving on to step 1:
7 divided by 902 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 902

Advancing to step 2:
If we divide 72 by 902, we get 0 and a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 902

Advancing to step 3:
724 divided by 902 is 0 with a remainder of 724.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 724 and we're left with 724.
Append the next digit (1) from the dividend to 724 and continue with: 7241 / 902

On to step 4:
7241 divided by 902 is 8 with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 7216 away from 7241, we end up with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 902

Step 5:
If we divide 251 by 902, we get 0 and a remainder of 251.
Write down 0 as next digit of the result. 
Result so far: 80.0
Deduct 0 from 251 and we're left with 251.
Fetch the next digit (5) from the dividend, attach it to 251 and continue: 2515 / 902

Advancing to step 6:
If we divide 2515 by 902, we get 2 and a remainder of 711.
Put 2 as the next digit of the answer. 
Result so far: 802.0
Subtracting 1804 from 2515 leaves us with 711.
Grab the next digit (0) from the dividend, add it to 711, then carry on: 7110 / 902

Going ahead to step 7:
902 can be fit into 7110 7 times, resulting in a remainder of 796.
Put 7 as the next digit of the answer. 
Result so far: 8027.0
The remainder is 796 after subtracting 6314 from 7110.
Fetch the next digit (2) from the dividend, attach it to 796 and continue: 7962 / 902

Advancing to step 8:
The number 902 fits into 7962 8 times, leaving a remainder of 746.
The next digit of our result is 8. 
Result so far: 80278.0
Subtracting 7216 from 7962 leaves us with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

On to step 9:
The number 902 fits into 7460 8 times, leaving a remainder of 244.
Write down 8 as next digit of the result. 
Result so far: 80278.8
If we subtract 7216 from 7460, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 10:
902 can be fit into 2440 2 times, resulting in a remainder of 636.
The next digit of our result is 2. 
Result so far: 80278.82
Subtract 1804 from 2440 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 11:
6360 divided by 902 is 7 with a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 80278.827
If we subtract 6314 from 6360, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
902 goes into 460 0 times with a remainder of 460.
Put 0 as the next digit of the answer. 
Result so far: 80278.827
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 13:
902 can be fit into 4600 5 times, resulting in a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 80278.82705
If we take 4510 away from 4600, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 14:
The number 902 fits into 900 0 times, leaving a remainder of 900.
Record the quotient 0 as the next digit in the result. 
Result so far: 80278.82705
The remainder is 900 after subtracting 0 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Moving on to step 15:
902 goes into 9000 9 times with a remainder of 882.
The number 9 becomes the next digit in our result. 
Result so far: 80278.8270509
Subtract 8118 from 9000 to get 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

Going ahead to step 16:
When dividing 8820 by 902, we get 9 with a remainder of 702.
Record the quotient 9 as the next digit in the result. 
Result so far: 80278.82705099
The remainder is 702 after subtracting 8118 from 8820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

After the division, we end up with 80278.82705099 and a remainder of 7.02e-07.
