We're dividing 21605272 by 739 
The aim is to understand the frequency of 739 in 21605272.

Let's proceed to step 1:
When dividing 2 by 739, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 739

On to step 2:
739 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 739

Let's proceed to step 3:
When dividing 216 by 739, we get 0 with a remainder of 216.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 216 to get 216.
Fetch the next digit (0) from the dividend, attach it to 216 and continue: 2160 / 739

Let's proceed to step 4:
739 goes into 2160 2 times with a remainder of 682.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1478 from 2160, we get 682.
Include the next digit (5) from the dividend after 682, then repeat: 6825 / 739

On to step 5:
When dividing 6825 by 739, we get 9 with a remainder of 174.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we subtract 6651 from 6825, we get 174.
Append the next digit (2) from the dividend to 174 and continue with: 1742 / 739

Step 6:
When dividing 1742 by 739, we get 2 with a remainder of 264.
Write down 2 as next digit of the result. 
Result so far: 292.0
Subtracting 1478 from 1742 leaves us with 264.
Fetch the next digit (7) from the dividend, attach it to 264 and continue: 2647 / 739

Advancing to step 7:
The number 739 fits into 2647 3 times, leaving a remainder of 430.
Use 3 as the next digit of our solution. 
Result so far: 2923.0
Subtract 2217 from 2647 to get 430.
Fetch the next digit (2) from the dividend, attach it to 430 and continue: 4302 / 739

Going ahead to step 8:
When dividing 4302 by 739, we get 5 with a remainder of 607.
Record the quotient 5 as the next digit in the result. 
Result so far: 29235.0
The remainder is 607 after subtracting 3695 from 4302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Going ahead to step 9:
The number 739 fits into 6070 8 times, leaving a remainder of 158.
Write down 8 as next digit of the result. 
Result so far: 29235.8
Subtracting 5912 from 6070 leaves us 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.

On to step 10:
The number 739 fits into 1580 2 times, leaving a remainder of 102.
Write down 2 as next digit of the result. 
Result so far: 29235.82
If we subtract 1478 from 1580, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 11:
When dividing 1020 by 739, we get 1 with a remainder of 281.
The next digit of our result is 1. 
Result so far: 29235.821
The remainder is 281 after subtracting 739 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 12:
If we divide 2810 by 739, we get 3 and a remainder of 593.
Record the quotient 3 as the next digit in the result. 
Result so far: 29235.8213
The remainder is 593 after subtracting 2217 from 2810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Advancing to step 13:
When dividing 5930 by 739, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 29235.82138
If we take 5912 away from 5930, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
When dividing 180 by 739, we get 0 with a remainder of 180.
The next digit of our result is 0. 
Result so far: 29235.82138
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 15:
1800 divided by 739 is 2 with a remainder of 322.
Use 2 as the next digit of our solution. 
Result so far: 29235.8213802
The remainder is 322 after subtracting 1478 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 16:
3220 divided by 739 is 4 with a remainder of 264.
Use 4 as the next digit of our solution. 
Result so far: 29235.82138024
If we take 2956 away from 3220, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

After the division, we end up with 29235.82138024 and a remainder of 2.64e-07.
