78406329 ÷ 998 
The aim is to understand the frequency of 998 in 78406329.

Going ahead to step 1:
The number 998 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 998

Let's proceed to step 2:
998 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 998

Going ahead to step 3:
998 can be fit into 784 0 times, resulting in a remainder of 784.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 784, we end up with 784.
Bring next digit (0) of the dividend behind the 784 and repeat the process: 7840 / 998

Step 4:
7840 divided by 998 is 7 with a remainder of 854.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 6986 away from 7840, we end up with 854.
Bring next digit (6) of the dividend behind the 854 and repeat the process: 8546 / 998

Advancing to step 5:
998 goes into 8546 8 times with a remainder of 562.
The next digit of our result is 8. 
Result so far: 78.0
If we take 7984 away from 8546, we end up with 562.
Append the next digit (3) from the dividend to 562 and continue with: 5623 / 998

Let's proceed to step 6:
998 can be fit into 5623 5 times, resulting in a remainder of 633.
Put 5 as the next digit of the answer. 
Result so far: 785.0
Subtract 4990 from 5623 to get 633.
Grab the next digit (2) from the dividend, add it to 633, then carry on: 6332 / 998

On to step 7:
When dividing 6332 by 998, we get 6 with a remainder of 344.
Write down 6 as next digit of the result. 
Result so far: 7856.0
Deduct 5988 from 6332 and we're left with 344.
Grab the next digit (9) from the dividend, add it to 344, then carry on: 3449 / 998

Moving on to step 8:
The number 998 fits into 3449 3 times, leaving a remainder of 455.
The number 3 becomes the next digit in our result. 
Result so far: 78563.0
The remainder is 455 after subtracting 2994 from 3449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Step 9:
998 can be fit into 4550 4 times, resulting in a remainder of 558.
Write down 4 as next digit of the result. 
Result so far: 78563.4
Subtracting 3992 from 4550 leaves us with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 10:
998 can be fit into 5580 5 times, resulting in a remainder of 590.
The number 5 becomes the next digit in our result. 
Result so far: 78563.45
If we take 4990 away from 5580, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 11:
The number 998 fits into 5900 5 times, leaving a remainder of 910.
Use 5 as the next digit of our solution. 
Result so far: 78563.455
If we subtract 4990 from 5900, we get 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

In conclusion, the division gives 78563.455 with a balance of 0.091.
