We look at the division of 2118690 by 989 
The aim is to understand the frequency of 989 in 2118690.

Let's proceed to step 1:
When dividing 2 by 989, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 989

Step 2:
If we divide 21 by 989, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 989

Step 3:
989 can be fit into 211 0 times, resulting in a remainder of 211.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 211 after subtracting 0 from 211.
Take the next digit (8) from the dividend and append it to 211, then repeat: 2118 / 989

On to step 4:
989 can be fit into 2118 2 times, resulting in a remainder of 140.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1978 from 2118 to get 140.
Grab the next digit (6) from the dividend, add it to 140, then carry on: 1406 / 989

Step 5:
If we divide 1406 by 989, we get 1 and a remainder of 417.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 989 from 1406 leaves us with 417.
Grab the next digit (9) from the dividend, add it to 417, then carry on: 4179 / 989

Going ahead to step 6:
4179 divided by 989 is 4 with a remainder of 223.
Put 4 as the next digit of the answer. 
Result so far: 214.0
If we take 3956 away from 4179, we end up with 223.
Grab the next digit (0) from the dividend, add it to 223, then carry on: 2230 / 989

Going ahead to step 7:
When dividing 2230 by 989, we get 2 with a remainder of 252.
The number 2 becomes the next digit in our result. 
Result so far: 2142.0
If we take 1978 away from 2230, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 8:
If we divide 2520 by 989, we get 2 and a remainder of 542.
The number 2 becomes the next digit in our result. 
Result so far: 2142.2
If we take 1978 away from 2520, we end up with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

On to step 9:
If we divide 5420 by 989, we get 5 and a remainder of 475.
Use 5 as the next digit of our solution. 
Result so far: 2142.25
If we take 4945 away from 5420, we end up with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 10:
989 goes into 4750 4 times with a remainder of 794.
The number 4 becomes the next digit in our result. 
Result so far: 2142.254
Subtract 3956 from 4750 to get 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Step 11:
989 can be fit into 7940 8 times, resulting in a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 2142.2548
If we subtract 7912 from 7940, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
280 divided by 989 is 0 with a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 2142.2548
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 13:
The number 989 fits into 2800 2 times, leaving a remainder of 822.
The number 2 becomes the next digit in our result. 
Result so far: 2142.254802
If we take 1978 away from 2800, we end up with 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Step 14:
The number 989 fits into 8220 8 times, leaving a remainder of 308.
Use 8 as the next digit of our solution. 
Result so far: 2142.2548028
Subtract 7912 from 8220 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 15:
989 goes into 3080 3 times with a remainder of 113.
The next digit of our result is 3. 
Result so far: 2142.25480283
If we subtract 2967 from 3080, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

In conclusion, the division gives 2142.25480283 with a balance of 1.13e-07.
