78374600 ÷ 498 
The aim is to understand the frequency of 498 in 78374600.

Going ahead to step 1:
When dividing 7 by 498, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 498

Moving on to step 2:
498 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 498

On to step 3:
If we divide 783 by 498, we get 1 and a remainder of 285.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 498 from 783 and we're left with 285.
Take the next digit (7) from the dividend and append it to 285, then repeat: 2857 / 498

Step 4:
2857 divided by 498 is 5 with a remainder of 367.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 2490 away from 2857, we end up with 367.
Append the next digit (4) from the dividend to 367 and continue with: 3674 / 498

Let's proceed to step 5:
When dividing 3674 by 498, we get 7 with a remainder of 188.
The next digit of our result is 7. 
Result so far: 157.0
If we take 3486 away from 3674, we end up with 188.
Fetch the next digit (6) from the dividend, attach it to 188 and continue: 1886 / 498

Advancing to step 6:
The number 498 fits into 1886 3 times, leaving a remainder of 392.
Use 3 as the next digit of our solution. 
Result so far: 1573.0
Deduct 1494 from 1886 and we're left with 392.
Append the next digit (0) from the dividend to 392 and continue with: 3920 / 498

Moving on to step 7:
498 can be fit into 3920 7 times, resulting in a remainder of 434.
Write down 7 as next digit of the result. 
Result so far: 15737.0
The remainder is 434 after subtracting 3486 from 3920.
Fetch the next digit (0) from the dividend, attach it to 434 and continue: 4340 / 498

Going ahead to step 8:
The number 498 fits into 4340 8 times, leaving a remainder of 356.
The next digit of our result is 8. 
Result so far: 157378.0
Deduct 3984 from 4340 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 9:
498 goes into 3560 7 times with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 157378.7
If we subtract 3486 from 3560, we 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.

On to step 10:
498 can be fit into 740 1 times, resulting in a remainder of 242.
Use 1 as the next digit of our solution. 
Result so far: 157378.71
Subtract 498 from 740 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 11:
498 can be fit into 2420 4 times, resulting in a remainder of 428.
The number 4 becomes the next digit in our result. 
Result so far: 157378.714
Subtract 1992 from 2420 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 12:
When dividing 4280 by 498, we get 8 with a remainder of 296.
Put 8 as the next digit of the answer. 
Result so far: 157378.7148
Deduct 3984 from 4280 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 13:
498 can be fit into 2960 5 times, resulting in a remainder of 470.
Write down 5 as next digit of the result. 
Result so far: 157378.71485
If we subtract 2490 from 2960, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 14:
If we divide 4700 by 498, we get 9 and a remainder of 218.
Record the quotient 9 as the next digit in the result. 
Result so far: 157378.714859
The remainder is 218 after subtracting 4482 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 15:
When dividing 2180 by 498, we get 4 with a remainder of 188.
The next digit of our result is 4. 
Result so far: 157378.7148594
Subtract 1992 from 2180 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 16:
The number 498 fits into 1880 3 times, leaving a remainder of 386.
Record the quotient 3 as the next digit in the result. 
Result so far: 157378.71485943
Subtract 1494 from 1880 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

The final result is 157378.71485943 with a remainder of 3.86e-07.
