Let's divide 11505986 by 902
The aim is to understand the frequency of 902 in 11505986.

On to step 1:
902 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 902

Going ahead to step 2:
902 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 902

On to step 3:
902 can be fit into 115 0 times, resulting in a remainder of 115.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 115 after subtracting 0 from 115.
Append the next digit (0) from the dividend to 115 and continue with: 1150 / 902

Let's proceed to step 4:
902 goes into 1150 1 times with a remainder of 248.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 902 from 1150 leaves us with 248.
Take the next digit (5) from the dividend and append it to 248, then repeat: 2485 / 902

Let's proceed to step 5:
If we divide 2485 by 902, we get 2 and a remainder of 681.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1804 from 2485, we get 681.
Take the next digit (9) from the dividend and append it to 681, then repeat: 6819 / 902

Moving on to step 6:
6819 divided by 902 is 7 with a remainder of 505.
Use 7 as the next digit of our solution. 
Result so far: 127.0
The remainder is 505 after subtracting 6314 from 6819.
Take the next digit (8) from the dividend and append it to 505, then repeat: 5058 / 902

Advancing to step 7:
The number 902 fits into 5058 5 times, leaving a remainder of 548.
The next digit of our result is 5. 
Result so far: 1275.0
If we take 4510 away from 5058, we end up with 548.
Bring next digit (6) of the dividend behind the 548 and repeat the process: 5486 / 902

Let's proceed to step 8:
If we divide 5486 by 902, we get 6 and a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 12756.0
Subtract 5412 from 5486 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 9:
740 divided by 902 is 0 with a remainder of 740.
The number 0 becomes the next digit in our result. 
Result so far: 12756.0
Subtract 0 from 740 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 10:
The number 902 fits into 7400 8 times, leaving a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 12756.08
If we subtract 7216 from 7400, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 11:
1840 divided by 902 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 12756.082
The remainder is 36 after subtracting 1804 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
When dividing 360 by 902, we get 0 with a remainder of 360.
The next digit of our result is 0. 
Result so far: 12756.082
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 13:
902 can be fit into 3600 3 times, resulting in a remainder of 894.
The number 3 becomes the next digit in our result. 
Result so far: 12756.08203
Subtracting 2706 from 3600 leaves us with 894.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8940, and continue the process.

On to step 14:
If we divide 8940 by 902, we get 9 and a remainder of 822.
Use 9 as the next digit of our solution. 
Result so far: 12756.082039
Subtract 8118 from 8940 to get 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Let's proceed to step 15:
902 goes into 8220 9 times with a remainder of 102.
The next digit of our result is 9. 
Result so far: 12756.0820399
Deduct 8118 from 8220 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Our division results in 12756.0820399 with a remaining 1.02e-06.
