We're dividing 537939 by 41 
The aim is to understand the frequency of 41 in 537939.

On to step 1:
5 divided by 41 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 41

Moving on to step 2:
41 goes into 53 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 41 from 53 to get 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 41

Step 3:
41 goes into 127 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 4 after subtracting 123 from 127.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 41

Advancing to step 4:
If we divide 49 by 41, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 131.0
Subtract 41 from 49 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 41

Advancing to step 5:
41 can be fit into 83 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 1312.0
If we subtract 82 from 83, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 41

Going ahead to step 6:
If we divide 19 by 41, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 13120.0
The remainder is 19 after subtracting 0 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
When dividing 190 by 41, we get 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 13120.4
Deduct 164 from 190 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
41 goes into 260 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 13120.46
Deduct 246 from 260 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
41 can be fit into 140 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 13120.463
If we take 123 away from 140, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 10:
If we divide 170 by 41, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 13120.4634
Subtract 164 from 170 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
If we divide 60 by 41, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 13120.46341
If we subtract 41 from 60, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
190 divided by 41 is 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 13120.463414
Deduct 164 from 190 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 13:
41 can be fit into 260 6 times, resulting in a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 13120.4634146
Subtract 246 from 260 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
140 divided by 41 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 13120.46341463
The remainder is 17 after subtracting 123 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 13120.46341463 and a remainder of 1.7e-08.
