Let's divide 51005868 by 890
The aim is to understand the frequency of 890 in 51005868.

On to step 1:
5 divided by 890 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 890

Going ahead to step 2:
890 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 890

Moving on to step 3:
510 divided by 890 is 0 with a remainder of 510.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 510 to get 510.
Include the next digit (0) from the dividend after 510, then repeat: 5100 / 890

Step 4:
890 goes into 5100 5 times with a remainder of 650.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 4450 from 5100 to get 650.
Bring next digit (5) of the dividend behind the 650 and repeat the process: 6505 / 890

Moving on to step 5:
If we divide 6505 by 890, we get 7 and a remainder of 275.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we subtract 6230 from 6505, we get 275.
Append the next digit (8) from the dividend to 275 and continue with: 2758 / 890

On to step 6:
890 goes into 2758 3 times with a remainder of 88.
The next digit of our result is 3. 
Result so far: 573.0
Deduct 2670 from 2758 and we're left with 88.
Bring next digit (6) of the dividend behind the 88 and repeat the process: 886 / 890

Step 7:
When dividing 886 by 890, we get 0 with a remainder of 886.
Put 0 as the next digit of the answer. 
Result so far: 5730.0
If we take 0 away from 886, we end up with 886.
Fetch the next digit (8) from the dividend, attach it to 886 and continue: 8868 / 890

Going ahead to step 8:
If we divide 8868 by 890, we get 9 and a remainder of 858.
Write down 9 as next digit of the result. 
Result so far: 57309.0
The remainder is 858 after subtracting 8010 from 8868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8580, and continue the process.

Moving on to step 9:
The number 890 fits into 8580 9 times, leaving a remainder of 570.
Write down 9 as next digit of the result. 
Result so far: 57309.9
If we subtract 8010 from 8580, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Moving on to step 10:
When dividing 5700 by 890, we get 6 with a remainder of 360.
The next digit of our result is 6. 
Result so far: 57309.96
Subtract 5340 from 5700 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 11:
890 goes into 3600 4 times with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 57309.964
If we take 3560 away from 3600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
890 goes into 400 0 times with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 57309.964
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 13:
890 goes into 4000 4 times with a remainder of 440.
The next digit of our result is 4. 
Result so far: 57309.96404
If we subtract 3560 from 4000, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 14:
890 goes into 4400 4 times with a remainder of 840.
Write down 4 as next digit of the result. 
Result so far: 57309.964044
Deduct 3560 from 4400 and we're left with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Our division results in 57309.964044 with a remaining 8.4e-05.
