We divide 21242709 by 737
The aim is to understand the frequency of 737 in 21242709.

Going ahead to step 1:
737 goes into 2 0 times with 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.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 737

On to step 2:
21 divided by 737 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 737

On to step 3:
737 goes into 212 0 times with a remainder of 212.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Take the next digit (4) from the dividend and append it to 212, then repeat: 2124 / 737

Step 4:
2124 divided by 737 is 2 with a remainder of 650.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1474 away from 2124, we end up with 650.
Grab the next digit (2) from the dividend, add it to 650, then carry on: 6502 / 737

Moving on to step 5:
When dividing 6502 by 737, we get 8 with a remainder of 606.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we subtract 5896 from 6502, we get 606.
Append the next digit (7) from the dividend to 606 and continue with: 6067 / 737

On to step 6:
When dividing 6067 by 737, we get 8 with a remainder of 171.
Record the quotient 8 as the next digit in the result. 
Result so far: 288.0
If we subtract 5896 from 6067, we get 171.
Include the next digit (0) from the dividend after 171, then repeat: 1710 / 737

Moving on to step 7:
1710 divided by 737 is 2 with a remainder of 236.
Use 2 as the next digit of our solution. 
Result so far: 2882.0
If we subtract 1474 from 1710, we get 236.
Include the next digit (9) from the dividend after 236, then repeat: 2369 / 737

Going ahead to step 8:
When dividing 2369 by 737, we get 3 with a remainder of 158.
Put 3 as the next digit of the answer. 
Result so far: 28823.0
Deduct 2211 from 2369 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 9:
If we divide 1580 by 737, we get 2 and a remainder of 106.
Write down 2 as next digit of the result. 
Result so far: 28823.2
If we subtract 1474 from 1580, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 10:
The number 737 fits into 1060 1 times, leaving a remainder of 323.
Record the quotient 1 as the next digit in the result. 
Result so far: 28823.21
Deduct 737 from 1060 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

On to step 11:
737 goes into 3230 4 times with a remainder of 282.
Record the quotient 4 as the next digit in the result. 
Result so far: 28823.214
If we take 2948 away from 3230, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 12:
2820 divided by 737 is 3 with a remainder of 609.
Use 3 as the next digit of our solution. 
Result so far: 28823.2143
If we take 2211 away from 2820, we end up with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Going ahead to step 13:
If we divide 6090 by 737, we get 8 and a remainder of 194.
The next digit of our result is 8. 
Result so far: 28823.21438
If we take 5896 away from 6090, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 14:
If we divide 1940 by 737, we get 2 and a remainder of 466.
Put 2 as the next digit of the answer. 
Result so far: 28823.214382
The remainder is 466 after subtracting 1474 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 15:
4660 divided by 737 is 6 with a remainder of 238.
Put 6 as the next digit of the answer. 
Result so far: 28823.2143826
The remainder is 238 after subtracting 4422 from 4660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 16:
When dividing 2380 by 737, we get 3 with a remainder of 169.
Write down 3 as next digit of the result. 
Result so far: 28823.21438263
If we subtract 2211 from 2380, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

The final result is 28823.21438263 with a remainder of 1.69e-07.
