18005621 divided by 988 
The aim is to understand the frequency of 988 in 18005621.

Advancing to step 1:
If we divide 1 by 988, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 988

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
Subtract 0 from 18 to get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 988

Advancing to step 3:
180 divided by 988 is 0 with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 180 to get 180.
Fetch the next digit (0) from the dividend, attach it to 180 and continue: 1800 / 988

Let's proceed to step 4:
988 can be fit into 1800 1 times, resulting in a remainder of 812.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 812 after subtracting 988 from 1800.
Append the next digit (5) from the dividend to 812 and continue with: 8125 / 988

Step 5:
The number 988 fits into 8125 8 times, leaving a remainder of 221.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 7904 from 8125, we get 221.
Take the next digit (6) from the dividend and append it to 221, then repeat: 2216 / 988

Moving on to step 6:
2216 divided by 988 is 2 with a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 182.0
If we take 1976 away from 2216, we end up with 240.
Append the next digit (2) from the dividend to 240 and continue with: 2402 / 988

On to step 7:
The number 988 fits into 2402 2 times, leaving a remainder of 426.
Record the quotient 2 as the next digit in the result. 
Result so far: 1822.0
Subtract 1976 from 2402 to get 426.
Include the next digit (1) from the dividend after 426, then repeat: 4261 / 988

On to step 8:
988 goes into 4261 4 times with a remainder of 309.
Use 4 as the next digit of our solution. 
Result so far: 18224.0
Deduct 3952 from 4261 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 9:
The number 988 fits into 3090 3 times, leaving a remainder of 126.
Write down 3 as next digit of the result. 
Result so far: 18224.3
Subtracting 2964 from 3090 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 10:
988 can be fit into 1260 1 times, resulting in a remainder of 272.
Put 1 as the next digit of the answer. 
Result so far: 18224.31
If we take 988 away from 1260, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 11:
988 goes into 2720 2 times with a remainder of 744.
Record the quotient 2 as the next digit in the result. 
Result so far: 18224.312
Deduct 1976 from 2720 and we're left with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Advancing to step 12:
7440 divided by 988 is 7 with a remainder of 524.
Use 7 as the next digit of our solution. 
Result so far: 18224.3127
If we subtract 6916 from 7440, we get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Going ahead to step 13:
The number 988 fits into 5240 5 times, leaving a remainder of 300.
The next digit of our result is 5. 
Result so far: 18224.31275
The remainder is 300 after subtracting 4940 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 14:
3000 divided by 988 is 3 with a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 18224.312753
Subtract 2964 from 3000 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 15:
988 goes into 360 0 times with a remainder of 360.
The next digit of our result is 0. 
Result so far: 18224.312753
Subtract 0 from 360 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.

Going ahead to step 16:
When dividing 3600 by 988, we get 3 with a remainder of 636.
Use 3 as the next digit of our solution. 
Result so far: 18224.31275303
If we subtract 2964 from 3600, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The final outcome is 18224.31275303, with a leftover of 6.36e-07.
