We're dividing 77909926 by 498 
The aim is to understand the frequency of 498 in 77909926.

Going ahead to step 1:
498 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 498

Advancing to step 2:
When dividing 77 by 498, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (9) from the dividend after 77, then repeat: 779 / 498

Let's proceed to step 3:
779 divided by 498 is 1 with a remainder of 281.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 498 from 779, we get 281.
Append the next digit (0) from the dividend to 281 and continue with: 2810 / 498

Let's proceed to step 4:
When dividing 2810 by 498, we get 5 with a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 2490 from 2810 leaves us with 320.
Grab the next digit (9) from the dividend, add it to 320, then carry on: 3209 / 498

On to step 5:
When dividing 3209 by 498, we get 6 with a remainder of 221.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
Subtracting 2988 from 3209 leaves us with 221.
Take the next digit (9) from the dividend and append it to 221, then repeat: 2219 / 498

Step 6:
When dividing 2219 by 498, we get 4 with a remainder of 227.
Use 4 as the next digit of our solution. 
Result so far: 1564.0
If we take 1992 away from 2219, we end up with 227.
Include the next digit (2) from the dividend after 227, then repeat: 2272 / 498

Moving on to step 7:
If we divide 2272 by 498, we get 4 and a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 15644.0
Deduct 1992 from 2272 and we're left with 280.
Take the next digit (6) from the dividend and append it to 280, then repeat: 2806 / 498

Going ahead to step 8:
2806 divided by 498 is 5 with a remainder of 316.
Put 5 as the next digit of the answer. 
Result so far: 156445.0
The remainder is 316 after subtracting 2490 from 2806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 9:
498 goes into 3160 6 times with a remainder of 172.
The number 6 becomes the next digit in our result. 
Result so far: 156445.6
If we subtract 2988 from 3160, we 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.

Moving on to step 10:
1720 divided by 498 is 3 with a remainder of 226.
Use 3 as the next digit of our solution. 
Result so far: 156445.63
Subtract 1494 from 1720 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 11:
If we divide 2260 by 498, we get 4 and a remainder of 268.
Put 4 as the next digit of the answer. 
Result so far: 156445.634
Deduct 1992 from 2260 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 12:
498 can be fit into 2680 5 times, resulting in a remainder of 190.
The next digit of our result is 5. 
Result so far: 156445.6345
If we subtract 2490 from 2680, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 13:
498 can be fit into 1900 3 times, resulting in a remainder of 406.
Record the quotient 3 as the next digit in the result. 
Result so far: 156445.63453
Subtract 1494 from 1900 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 14:
498 goes into 4060 8 times with a remainder of 76.
The next digit of our result is 8. 
Result so far: 156445.634538
The remainder is 76 after subtracting 3984 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 15:
498 goes into 760 1 times with a remainder of 262.
Record the quotient 1 as the next digit in the result. 
Result so far: 156445.6345381
The remainder is 262 after subtracting 498 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 16:
498 goes into 2620 5 times with a remainder of 130.
The next digit of our result is 5. 
Result so far: 156445.63453815
Subtracting 2490 from 2620 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final outcome is 156445.63453815, with a leftover of 1.3e-07.
