90205137 divided by 308 
The aim is to understand the frequency of 308 in 90205137.

Advancing to step 1:
308 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 308

Advancing to step 2:
308 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Bring next digit (2) of the dividend behind the 90 and repeat the process: 902 / 308

Advancing to step 3:
When dividing 902 by 308, we get 2 with a remainder of 286.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 616 away from 902, we end up with 286.
Grab the next digit (0) from the dividend, add it to 286, then carry on: 2860 / 308

Advancing to step 4:
308 can be fit into 2860 9 times, resulting in a remainder of 88.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Deduct 2772 from 2860 and we're left with 88.
Fetch the next digit (5) from the dividend, attach it to 88 and continue: 885 / 308

Advancing to step 5:
The number 308 fits into 885 2 times, leaving a remainder of 269.
Use 2 as the next digit of our solution. 
Result so far: 292.0
If we subtract 616 from 885, we get 269.
Append the next digit (1) from the dividend to 269 and continue with: 2691 / 308

Let's proceed to step 6:
2691 divided by 308 is 8 with a remainder of 227.
The number 8 becomes the next digit in our result. 
Result so far: 2928.0
The remainder is 227 after subtracting 2464 from 2691.
Take the next digit (3) from the dividend and append it to 227, then repeat: 2273 / 308

On to step 7:
308 goes into 2273 7 times with a remainder of 117.
Put 7 as the next digit of the answer. 
Result so far: 29287.0
If we take 2156 away from 2273, we end up with 117.
Append the next digit (7) from the dividend to 117 and continue with: 1177 / 308

Step 8:
308 goes into 1177 3 times with a remainder of 253.
Use 3 as the next digit of our solution. 
Result so far: 292873.0
Subtracting 924 from 1177 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 9:
308 can be fit into 2530 8 times, resulting in a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 292873.8
If we take 2464 away from 2530, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
660 divided by 308 is 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 292873.82
Deduct 616 from 660 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
If we divide 440 by 308, we get 1 and a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 292873.821
Subtract 308 from 440 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 12:
308 can be fit into 1320 4 times, resulting in a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 292873.8214
Subtract 1232 from 1320 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 13:
308 can be fit into 880 2 times, resulting in a remainder of 264.
Use 2 as the next digit of our solution. 
Result so far: 292873.82142
The remainder is 264 after subtracting 616 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 14:
308 can be fit into 2640 8 times, resulting in a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 292873.821428
Subtracting 2464 from 2640 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 15:
The number 308 fits into 1760 5 times, leaving a remainder of 220.
The next digit of our result is 5. 
Result so far: 292873.8214285
The remainder is 220 after subtracting 1540 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 16:
The number 308 fits into 2200 7 times, leaving a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 292873.82142857
Subtract 2156 from 2200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 292873.82142857 with a remainder of 4.4e-08.
