We're dividing 1888604 by 988 
The aim is to understand the frequency of 988 in 1888604.

Advancing to step 1:
When dividing 1 by 988, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 988

Advancing to step 2:
988 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 988

Step 3:
The number 988 fits into 188 0 times, leaving a remainder of 188.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 188 and we're left with 188.
Include the next digit (8) from the dividend after 188, then repeat: 1888 / 988

Let's proceed to step 4:
988 can be fit into 1888 1 times, resulting in a remainder of 900.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 988 from 1888 to get 900.
Append the next digit (6) from the dividend to 900 and continue with: 9006 / 988

On to step 5:
988 can be fit into 9006 9 times, resulting in a remainder of 114.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 8892 from 9006 and we're left with 114.
Include the next digit (0) from the dividend after 114, then repeat: 1140 / 988

Step 6:
The number 988 fits into 1140 1 times, leaving a remainder of 152.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
Subtract 988 from 1140 to get 152.
Include the next digit (4) from the dividend after 152, then repeat: 1524 / 988

Step 7:
1524 divided by 988 is 1 with a remainder of 536.
Use 1 as the next digit of our solution. 
Result so far: 1911.0
Subtract 988 from 1524 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 8:
If we divide 5360 by 988, we get 5 and a remainder of 420.
Use 5 as the next digit of our solution. 
Result so far: 1911.5
Subtracting 4940 from 5360 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.

Step 9:
988 can be fit into 4200 4 times, resulting in a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 1911.54
Subtract 3952 from 4200 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 10:
2480 divided by 988 is 2 with a remainder of 504.
Use 2 as the next digit of our solution. 
Result so far: 1911.542
If we take 1976 away from 2480, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 11:
988 can be fit into 5040 5 times, resulting in a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 1911.5425
If we take 4940 away from 5040, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 12:
1000 divided by 988 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1911.54251
If we take 988 away from 1000, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
If we divide 120 by 988, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 1911.54251
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 14:
988 goes into 1200 1 times with a remainder of 212.
The number 1 becomes the next digit in our result. 
Result so far: 1911.5425101
If we take 988 away from 1200, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 15:
2120 divided by 988 is 2 with a remainder of 144.
The next digit of our result is 2. 
Result so far: 1911.54251012
Deduct 1976 from 2120 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

After the division, we end up with 1911.54251012 and a remainder of 1.44e-07.
