591516 divided by 37 
The aim is to understand the frequency of 37 in 591516.

Step 1:
37 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 37

On to step 2:
If we divide 59 by 37, we get 1 and a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 37 from 59 leaves us with 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 37

On to step 3:
221 divided by 37 is 5 with a remainder of 36.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 185 from 221 and we're left with 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 37

Let's proceed to step 4:
When dividing 365 by 37, we get 9 with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
If we take 333 away from 365, we end up with 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 37

Moving on to step 5:
321 divided by 37 is 8 with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 1598.0
If we take 296 away from 321, we end up with 25.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 37

Advancing to step 6:
The number 37 fits into 256 6 times, leaving a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 15986.0
Subtracting 222 from 256 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
340 divided by 37 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 15986.9
Subtracting 333 from 340 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
When dividing 70 by 37, we get 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 15986.91
Deduct 37 from 70 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
When dividing 330 by 37, we get 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 15986.918
Subtract 296 from 330 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
If we divide 340 by 37, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 15986.9189
Subtracting 333 from 340 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
When dividing 70 by 37, we get 1 with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 15986.91891
Subtracting 37 from 70 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 12:
37 goes into 330 8 times with a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 15986.918918
The remainder is 34 after subtracting 296 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
340 divided by 37 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 15986.9189189
The remainder is 7 after subtracting 333 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
If we divide 70 by 37, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 15986.91891891
Subtract 37 from 70 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

After the division, we end up with 15986.91891891 and a remainder of 3.3e-08.
