37213419 divided by 37 
The aim is to understand the frequency of 37 in 37213419.

Let's proceed to step 1:
If we divide 3 by 37, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 37

Going ahead to step 2:
The number 37 fits into 37 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 37 from 37 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 37

Moving on to step 3:
37 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 37

Step 4:
37 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 100.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 37

On to step 5:
37 goes into 213 5 times with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 1005.0
Deduct 185 from 213 and we're left with 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 37

Let's proceed to step 6:
284 divided by 37 is 7 with a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 10057.0
Subtracting 259 from 284 leaves us with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 37

Let's proceed to step 7:
The number 37 fits into 251 6 times, leaving a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 100576.0
If we subtract 222 from 251, we get 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 37

Going ahead to step 8:
When dividing 299 by 37, we get 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 1005768.0
If we take 296 away from 299, 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.

On to step 9:
37 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1005768.0
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.

Going ahead to step 10:
37 can be fit into 300 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 1005768.08
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.

Moving on to step 11:
The number 37 fits into 40 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1005768.081
If we subtract 37 from 40, we 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.

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: 1005768.081
If we subtract 0 from 30, we 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.

Going ahead to step 13:
300 divided by 37 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1005768.08108
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.

On to step 14:
If we divide 40 by 37, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1005768.081081
The remainder is 3 after subtracting 37 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 15:
When dividing 30 by 37, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1005768.081081
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.

Moving on to step 16:
When dividing 300 by 37, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 1005768.08108108
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.

The final result is 1005768.08108108 with a remainder of 4e-09.
