78718366 ÷ 890 
The aim is to understand the frequency of 890 in 78718366.

Step 1:
The number 890 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 890

Moving on to step 2:
890 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 890

Advancing to step 3:
If we divide 787 by 890, we get 0 and a remainder of 787.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 787 after subtracting 0 from 787.
Append the next digit (1) from the dividend to 787 and continue with: 7871 / 890

Step 4:
The number 890 fits into 7871 8 times, leaving a remainder of 751.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 7120 from 7871 and we're left with 751.
Bring next digit (8) of the dividend behind the 751 and repeat the process: 7518 / 890

Step 5:
If we divide 7518 by 890, we get 8 and a remainder of 398.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Subtract 7120 from 7518 to get 398.
Append the next digit (3) from the dividend to 398 and continue with: 3983 / 890

Advancing to step 6:
3983 divided by 890 is 4 with a remainder of 423.
Use 4 as the next digit of our solution. 
Result so far: 884.0
The remainder is 423 after subtracting 3560 from 3983.
Include the next digit (6) from the dividend after 423, then repeat: 4236 / 890

Advancing to step 7:
890 goes into 4236 4 times with a remainder of 676.
The number 4 becomes the next digit in our result. 
Result so far: 8844.0
If we take 3560 away from 4236, we end up with 676.
Fetch the next digit (6) from the dividend, attach it to 676 and continue: 6766 / 890

Moving on to step 8:
If we divide 6766 by 890, we get 7 and a remainder of 536.
Record the quotient 7 as the next digit in the result. 
Result so far: 88447.0
If we take 6230 away from 6766, we end up with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 9:
The number 890 fits into 5360 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 88447.6
If we subtract 5340 from 5360, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
When dividing 200 by 890, we get 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 88447.6
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
890 goes into 2000 2 times with a remainder of 220.
The next digit of our result is 2. 
Result so far: 88447.602
The remainder is 220 after subtracting 1780 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 12:
2200 divided by 890 is 2 with a remainder of 420.
Record the quotient 2 as the next digit in the result. 
Result so far: 88447.6022
Subtracting 1780 from 2200 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The final outcome is 88447.6022, with a leftover of 0.0042.
