We divide 37071419 by 815
The aim is to understand the frequency of 815 in 37071419.

On to step 1:
If we divide 3 by 815, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 815

Let's proceed to step 2:
37 divided by 815 is 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 815

Going ahead to step 3:
815 goes into 370 0 times with a remainder of 370.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 370 leaves us with 370.
Fetch the next digit (7) from the dividend, attach it to 370 and continue: 3707 / 815

On to step 4:
If we divide 3707 by 815, we get 4 and a remainder of 447.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 3260 from 3707, we get 447.
Bring next digit (1) of the dividend behind the 447 and repeat the process: 4471 / 815

Advancing to step 5:
The number 815 fits into 4471 5 times, leaving a remainder of 396.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we take 4075 away from 4471, we end up with 396.
Fetch the next digit (4) from the dividend, attach it to 396 and continue: 3964 / 815

Advancing to step 6:
If we divide 3964 by 815, we get 4 and a remainder of 704.
Put 4 as the next digit of the answer. 
Result so far: 454.0
Deduct 3260 from 3964 and we're left with 704.
Grab the next digit (1) from the dividend, add it to 704, then carry on: 7041 / 815

On to step 7:
When dividing 7041 by 815, we get 8 with a remainder of 521.
The next digit of our result is 8. 
Result so far: 4548.0
If we take 6520 away from 7041, we end up with 521.
Include the next digit (9) from the dividend after 521, then repeat: 5219 / 815

Advancing to step 8:
If we divide 5219 by 815, we get 6 and a remainder of 329.
The number 6 becomes the next digit in our result. 
Result so far: 45486.0
The remainder is 329 after subtracting 4890 from 5219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 9:
When dividing 3290 by 815, we get 4 with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 45486.4
The remainder is 30 after subtracting 3260 from 3290.
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:
300 divided by 815 is 0 with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 45486.4
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
815 can be fit into 3000 3 times, resulting in a remainder of 555.
Record the quotient 3 as the next digit in the result. 
Result so far: 45486.403
The remainder is 555 after subtracting 2445 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Going ahead to step 12:
815 goes into 5550 6 times with a remainder of 660.
Use 6 as the next digit of our solution. 
Result so far: 45486.4036
Subtract 4890 from 5550 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 13:
When dividing 6600 by 815, we get 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 45486.40368
Deduct 6520 from 6600 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
815 can be fit into 800 0 times, resulting in a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 45486.40368
If we subtract 0 from 800, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 15:
815 can be fit into 8000 9 times, resulting in a remainder of 665.
The number 9 becomes the next digit in our result. 
Result so far: 45486.4036809
Subtracting 7335 from 8000 leaves us with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Going ahead to step 16:
815 can be fit into 6650 8 times, resulting in a remainder of 130.
Record the quotient 8 as the next digit in the result. 
Result so far: 45486.40368098
If we subtract 6520 from 6650, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final outcome is 45486.40368098, with a leftover of 1.3e-07.
