We look at the division of 37953173 by 413 
The aim is to understand the frequency of 413 in 37953173.

Let's proceed to step 1:
If we divide 3 by 413, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 413

Step 2:
When dividing 37 by 413, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 413

On to step 3:
The number 413 fits into 379 0 times, leaving a remainder of 379.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 379 and we're left with 379.
Grab the next digit (5) from the dividend, add it to 379, then carry on: 3795 / 413

Moving on to step 4:
3795 divided by 413 is 9 with a remainder of 78.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 3717 from 3795 and we're left with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 413

Going ahead to step 5:
If we divide 783 by 413, we get 1 and a remainder of 370.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 413 from 783 leaves us with 370.
Append the next digit (1) from the dividend to 370 and continue with: 3701 / 413

Going ahead to step 6:
The number 413 fits into 3701 8 times, leaving a remainder of 397.
Record the quotient 8 as the next digit in the result. 
Result so far: 918.0
Subtracting 3304 from 3701 leaves us with 397.
Grab the next digit (7) from the dividend, add it to 397, then carry on: 3977 / 413

Going ahead to step 7:
413 goes into 3977 9 times with a remainder of 260.
Put 9 as the next digit of the answer. 
Result so far: 9189.0
The remainder is 260 after subtracting 3717 from 3977.
Grab the next digit (3) from the dividend, add it to 260, then carry on: 2603 / 413

Let's proceed to step 8:
413 can be fit into 2603 6 times, resulting in a remainder of 125.
The number 6 becomes the next digit in our result. 
Result so far: 91896.0
Subtract 2478 from 2603 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 9:
If we divide 1250 by 413, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 91896.3
If we subtract 1239 from 1250, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
If we divide 110 by 413, we get 0 and a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 91896.3
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 11:
413 goes into 1100 2 times with a remainder of 274.
Put 2 as the next digit of the answer. 
Result so far: 91896.302
If we take 826 away from 1100, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 12:
The number 413 fits into 2740 6 times, leaving a remainder of 262.
Use 6 as the next digit of our solution. 
Result so far: 91896.3026
Subtract 2478 from 2740 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 13:
413 goes into 2620 6 times with a remainder of 142.
Record the quotient 6 as the next digit in the result. 
Result so far: 91896.30266
If we subtract 2478 from 2620, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Our division results in 91896.30266 with a remaining 0.000142.
