86846506 ÷ 998 
The aim is to understand the frequency of 998 in 86846506.

Step 1:
If we divide 8 by 998, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 998

Moving on to step 2:
998 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 998

Let's proceed to step 3:
When dividing 868 by 998, we get 0 with a remainder of 868.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 868 after subtracting 0 from 868.
Take the next digit (4) from the dividend and append it to 868, then repeat: 8684 / 998

Step 4:
998 goes into 8684 8 times with a remainder of 700.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 7984 away from 8684, we end up with 700.
Fetch the next digit (6) from the dividend, attach it to 700 and continue: 7006 / 998

Step 5:
7006 divided by 998 is 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we subtract 6986 from 7006, we get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 998

Step 6:
If we divide 205 by 998, we get 0 and a remainder of 205.
Use 0 as the next digit of our solution. 
Result so far: 870.0
Deduct 0 from 205 and we're left with 205.
Grab the next digit (0) from the dividend, add it to 205, then carry on: 2050 / 998

On to step 7:
If we divide 2050 by 998, we get 2 and a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 8702.0
If we take 1996 away from 2050, we end up with 54.
Append the next digit (6) from the dividend to 54 and continue with: 546 / 998

On to step 8:
When dividing 546 by 998, we get 0 with a remainder of 546.
Record the quotient 0 as the next digit in the result. 
Result so far: 87020.0
If we take 0 away from 546, we end up with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

On to step 9:
When dividing 5460 by 998, we get 5 with a remainder of 470.
Write down 5 as next digit of the result. 
Result so far: 87020.5
Subtracting 4990 from 5460 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 10:
If we divide 4700 by 998, we get 4 and a remainder of 708.
Put 4 as the next digit of the answer. 
Result so far: 87020.54
Subtracting 3992 from 4700 leaves us with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Step 11:
When dividing 7080 by 998, we get 7 with a remainder of 94.
Write down 7 as next digit of the result. 
Result so far: 87020.547
Subtract 6986 from 7080 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 12:
940 divided by 998 is 0 with a remainder of 940.
Put 0 as the next digit of the answer. 
Result so far: 87020.547
Subtracting 0 from 940 leaves us with 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Let's proceed to step 13:
When dividing 9400 by 998, we get 9 with a remainder of 418.
Use 9 as the next digit of our solution. 
Result so far: 87020.54709
If we take 8982 away from 9400, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 14:
998 goes into 4180 4 times with a remainder of 188.
The number 4 becomes the next digit in our result. 
Result so far: 87020.547094
Subtract 3992 from 4180 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.

Step 15:
1880 divided by 998 is 1 with a remainder of 882.
Write down 1 as next digit of the result. 
Result so far: 87020.5470941
Subtracting 998 from 1880 leaves us with 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

Going ahead to step 16:
8820 divided by 998 is 8 with a remainder of 836.
Put 8 as the next digit of the answer. 
Result so far: 87020.54709418
Subtracting 7984 from 8820 leaves us with 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Our division results in 87020.54709418 with a remaining 8.36e-07.
