Let's divide 644157 by 37
The aim is to understand the frequency of 37 in 644157.

On to step 1:
If we divide 6 by 37, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 37

Let's proceed to step 2:
When dividing 64 by 37, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
If we take 37 away from 64, we end up with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 37

Let's proceed to step 3:
37 goes into 274 7 times with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 259 from 274 to get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 37

Let's proceed to step 4:
The number 37 fits into 151 4 times, leaving a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 174.0
Deduct 148 from 151 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 37

Advancing to step 5:
When dividing 35 by 37, we get 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 1740.0
If we subtract 0 from 35, we get 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 37

Advancing to step 6:
37 can be fit into 357 9 times, resulting in a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 17409.0
Subtracting 333 from 357 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
37 can be fit into 240 6 times, resulting in a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 17409.6
If we subtract 222 from 240, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
The number 37 fits into 180 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 17409.64
If we take 148 away from 180, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
320 divided by 37 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 17409.648
If we subtract 296 from 320, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
When dividing 240 by 37, we get 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 17409.6486
Subtracting 222 from 240 leaves us 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.

Let's proceed to step 11:
37 can be fit into 180 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 17409.64864
Subtract 148 from 180 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
The number 37 fits into 320 8 times, leaving a remainder of 24.
The next digit of our result is 8. 
Result so far: 17409.648648
Subtract 296 from 320 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
The number 37 fits into 240 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 17409.6486486
If we subtract 222 from 240, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
When dividing 180 by 37, we get 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 17409.64864864
The remainder is 32 after subtracting 148 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 17409.64864864 with a remaining 3.2e-08.
