We divide 21142579 by 988
The aim is to understand the frequency of 988 in 21142579.

Let's proceed to step 1:
988 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 988

Going ahead to step 2:
988 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 988

Let's proceed to step 3:
988 goes into 211 0 times with a remainder of 211.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 211, we end up with 211.
Append the next digit (4) from the dividend to 211 and continue with: 2114 / 988

Advancing to step 4:
When dividing 2114 by 988, we get 2 with a remainder of 138.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1976 from 2114 to get 138.
Take the next digit (2) from the dividend and append it to 138, then repeat: 1382 / 988

Moving on to step 5:
The number 988 fits into 1382 1 times, leaving a remainder of 394.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 988 from 1382 and we're left with 394.
Bring next digit (5) of the dividend behind the 394 and repeat the process: 3945 / 988

Let's proceed to step 6:
988 goes into 3945 3 times with a remainder of 981.
Put 3 as the next digit of the answer. 
Result so far: 213.0
If we take 2964 away from 3945, we end up with 981.
Append the next digit (7) from the dividend to 981 and continue with: 9817 / 988

Going ahead to step 7:
988 can be fit into 9817 9 times, resulting in a remainder of 925.
Write down 9 as next digit of the result. 
Result so far: 2139.0
Deduct 8892 from 9817 and we're left with 925.
Take the next digit (9) from the dividend and append it to 925, then repeat: 9259 / 988

Moving on to step 8:
9259 divided by 988 is 9 with a remainder of 367.
The number 9 becomes the next digit in our result. 
Result so far: 21399.0
If we take 8892 away from 9259, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 9:
3670 divided by 988 is 3 with a remainder of 706.
The number 3 becomes the next digit in our result. 
Result so far: 21399.3
Subtracting 2964 from 3670 leaves us with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Advancing to step 10:
988 goes into 7060 7 times with a remainder of 144.
Put 7 as the next digit of the answer. 
Result so far: 21399.37
Deduct 6916 from 7060 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.

On to step 11:
The number 988 fits into 1440 1 times, leaving a remainder of 452.
The next digit of our result is 1. 
Result so far: 21399.371
Subtract 988 from 1440 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 12:
988 goes into 4520 4 times with a remainder of 568.
The number 4 becomes the next digit in our result. 
Result so far: 21399.3714
The remainder is 568 after subtracting 3952 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Let's proceed to step 13:
The number 988 fits into 5680 5 times, leaving a remainder of 740.
Record the quotient 5 as the next digit in the result. 
Result so far: 21399.37145
Subtracting 4940 from 5680 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 14:
The number 988 fits into 7400 7 times, leaving a remainder of 484.
Write down 7 as next digit of the result. 
Result so far: 21399.371457
If we take 6916 away from 7400, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 15:
When dividing 4840 by 988, we get 4 with a remainder of 888.
Record the quotient 4 as the next digit in the result. 
Result so far: 21399.3714574
Subtract 3952 from 4840 to get 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

Step 16:
When dividing 8880 by 988, we get 8 with a remainder of 976.
Put 8 as the next digit of the answer. 
Result so far: 21399.37145748
Subtract 7904 from 8880 to get 976.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9760, and continue the process.

After the division, we end up with 21399.37145748 and a remainder of 9.76e-07.
