513590 divided by 37 
The aim is to understand the frequency of 37 in 513590.

Going ahead to step 1:
The number 37 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 37

On to step 2:
37 goes into 51 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 37 from 51 to get 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 37

On to step 3:
143 divided by 37 is 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 111 from 143 and we're left with 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 37

Step 4:
37 goes into 325 8 times with a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Subtract 296 from 325 to get 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 37

On to step 5:
The number 37 fits into 299 8 times, leaving a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 1388.0
The remainder is 3 after subtracting 296 from 299.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 37

Advancing to step 6:
37 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 13880.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
If we divide 300 by 37, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 13880.8
Deduct 296 from 300 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
If we divide 40 by 37, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 13880.81
Deduct 37 from 40 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
37 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 13880.81
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
37 can be fit into 300 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 13880.8108
If we take 296 away from 300, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
40 divided by 37 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 13880.81081
If we take 37 away from 40, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
37 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 13880.81081
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
If we divide 300 by 37, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 13880.8108108
Subtracting 296 from 300 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
37 goes into 40 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 13880.81081081
Subtract 37 from 40 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 13880.81081081 and a remainder of 3e-09.
