We divide 3797234 by 644
The aim is to understand the frequency of 644 in 3797234.

On to step 1:
When dividing 3 by 644, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 644

Going ahead to step 2:
37 divided by 644 is 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 644

Step 3:
The number 644 fits into 379 0 times, leaving a remainder of 379.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 379, we end up with 379.
Include the next digit (7) from the dividend after 379, then repeat: 3797 / 644

Let's proceed to step 4:
644 goes into 3797 5 times with a remainder of 577.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 3220 from 3797, we get 577.
Fetch the next digit (2) from the dividend, attach it to 577 and continue: 5772 / 644

Going ahead to step 5:
5772 divided by 644 is 8 with a remainder of 620.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Deduct 5152 from 5772 and we're left with 620.
Grab the next digit (3) from the dividend, add it to 620, then carry on: 6203 / 644

Going ahead to step 6:
644 can be fit into 6203 9 times, resulting in a remainder of 407.
The number 9 becomes the next digit in our result. 
Result so far: 589.0
Subtracting 5796 from 6203 leaves us with 407.
Take the next digit (4) from the dividend and append it to 407, then repeat: 4074 / 644

Let's proceed to step 7:
If we divide 4074 by 644, we get 6 and a remainder of 210.
Record the quotient 6 as the next digit in the result. 
Result so far: 5896.0
Subtract 3864 from 4074 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 8:
When dividing 2100 by 644, we get 3 with a remainder of 168.
Use 3 as the next digit of our solution. 
Result so far: 5896.3
If we take 1932 away from 2100, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 9:
When dividing 1680 by 644, we get 2 with a remainder of 392.
Record the quotient 2 as the next digit in the result. 
Result so far: 5896.32
Subtracting 1288 from 1680 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 10:
When dividing 3920 by 644, we get 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 5896.326
Subtract 3864 from 3920 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
When dividing 560 by 644, we get 0 with a remainder of 560.
The next digit of our result is 0. 
Result so far: 5896.326
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 12:
644 goes into 5600 8 times with a remainder of 448.
Put 8 as the next digit of the answer. 
Result so far: 5896.32608
The remainder is 448 after subtracting 5152 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 13:
644 can be fit into 4480 6 times, resulting in a remainder of 616.
Use 6 as the next digit of our solution. 
Result so far: 5896.326086
If we take 3864 away from 4480, we end up with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 14:
6160 divided by 644 is 9 with a remainder of 364.
Put 9 as the next digit of the answer. 
Result so far: 5896.3260869
If we subtract 5796 from 6160, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 15:
If we divide 3640 by 644, we get 5 and a remainder of 420.
Record the quotient 5 as the next digit in the result. 
Result so far: 5896.32608695
If we take 3220 away from 3640, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

In conclusion, the division gives 5896.32608695 with a balance of 4.2e-07.
