We look at the division of 87093937 by 890 
The aim is to understand the frequency of 890 in 87093937.

On to step 1:
890 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 890

Advancing to step 2:
When dividing 87 by 890, we get 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 890

Let's proceed to step 3:
890 can be fit into 870 0 times, resulting in a remainder of 870.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 870, we get 870.
Append the next digit (9) from the dividend to 870 and continue with: 8709 / 890

Moving on to step 4:
The number 890 fits into 8709 9 times, leaving a remainder of 699.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 699 after subtracting 8010 from 8709.
Include the next digit (3) from the dividend after 699, then repeat: 6993 / 890

Going ahead to step 5:
The number 890 fits into 6993 7 times, leaving a remainder of 763.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtract 6230 from 6993 to get 763.
Include the next digit (9) from the dividend after 763, then repeat: 7639 / 890

Moving on to step 6:
If we divide 7639 by 890, we get 8 and a remainder of 519.
Put 8 as the next digit of the answer. 
Result so far: 978.0
Subtracting 7120 from 7639 leaves us with 519.
Include the next digit (3) from the dividend after 519, then repeat: 5193 / 890

On to step 7:
If we divide 5193 by 890, we get 5 and a remainder of 743.
Put 5 as the next digit of the answer. 
Result so far: 9785.0
If we subtract 4450 from 5193, we get 743.
Include the next digit (7) from the dividend after 743, then repeat: 7437 / 890

Let's proceed to step 8:
890 can be fit into 7437 8 times, resulting in a remainder of 317.
Write down 8 as next digit of the result. 
Result so far: 97858.0
Subtract 7120 from 7437 to get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 9:
When dividing 3170 by 890, we get 3 with a remainder of 500.
The next digit of our result is 3. 
Result so far: 97858.3
Subtract 2670 from 3170 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 10:
The number 890 fits into 5000 5 times, leaving a remainder of 550.
Record the quotient 5 as the next digit in the result. 
Result so far: 97858.35
If we take 4450 away from 5000, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 11:
890 can be fit into 5500 6 times, resulting in a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 97858.356
If we subtract 5340 from 5500, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 12:
The number 890 fits into 1600 1 times, leaving a remainder of 710.
The next digit of our result is 1. 
Result so far: 97858.3561
The remainder is 710 after subtracting 890 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 13:
The number 890 fits into 7100 7 times, leaving a remainder of 870.
The number 7 becomes the next digit in our result. 
Result so far: 97858.35617
Deduct 6230 from 7100 and we're left with 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

Step 14:
When dividing 8700 by 890, we get 9 with a remainder of 690.
The number 9 becomes the next digit in our result. 
Result so far: 97858.356179
If we take 8010 away from 8700, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 15:
If we divide 6900 by 890, we get 7 and a remainder of 670.
The next digit of our result is 7. 
Result so far: 97858.3561797
The remainder is 670 after subtracting 6230 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 16:
890 goes into 6700 7 times with a remainder of 470.
Write down 7 as next digit of the result. 
Result so far: 97858.35617977
If we subtract 6230 from 6700, 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.

After the division, we end up with 97858.35617977 and a remainder of 4.7e-07.
