We divide 29638139 by 642
The aim is to understand the frequency of 642 in 29638139.

Going ahead to step 1:
The number 642 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 642

Let's proceed to step 2:
29 divided by 642 is 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 642

Going ahead to step 3:
642 can be fit into 296 0 times, resulting in a remainder of 296.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 296 after subtracting 0 from 296.
Grab the next digit (3) from the dividend, add it to 296, then carry on: 2963 / 642

Going ahead to step 4:
642 goes into 2963 4 times with a remainder of 395.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 2568 away from 2963, we end up with 395.
Take the next digit (8) from the dividend and append it to 395, then repeat: 3958 / 642

Step 5:
642 can be fit into 3958 6 times, resulting in a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Deduct 3852 from 3958 and we're left with 106.
Grab the next digit (1) from the dividend, add it to 106, then carry on: 1061 / 642

Moving on to step 6:
The number 642 fits into 1061 1 times, leaving a remainder of 419.
Use 1 as the next digit of our solution. 
Result so far: 461.0
If we take 642 away from 1061, we end up with 419.
Bring next digit (3) of the dividend behind the 419 and repeat the process: 4193 / 642

On to step 7:
642 can be fit into 4193 6 times, resulting in a remainder of 341.
Record the quotient 6 as the next digit in the result. 
Result so far: 4616.0
The remainder is 341 after subtracting 3852 from 4193.
Bring next digit (9) of the dividend behind the 341 and repeat the process: 3419 / 642

Moving on to step 8:
642 can be fit into 3419 5 times, resulting in a remainder of 209.
The next digit of our result is 5. 
Result so far: 46165.0
Subtract 3210 from 3419 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 9:
2090 divided by 642 is 3 with a remainder of 164.
Write down 3 as next digit of the result. 
Result so far: 46165.3
If we take 1926 away from 2090, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 10:
If we divide 1640 by 642, we get 2 and a remainder of 356.
Write down 2 as next digit of the result. 
Result so far: 46165.32
Subtract 1284 from 1640 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 11:
If we divide 3560 by 642, we get 5 and a remainder of 350.
The next digit of our result is 5. 
Result so far: 46165.325
If we subtract 3210 from 3560, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 12:
642 can be fit into 3500 5 times, resulting in a remainder of 290.
Record the quotient 5 as the next digit in the result. 
Result so far: 46165.3255
If we subtract 3210 from 3500, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The final outcome is 46165.3255, with a leftover of 0.0029.
