We look at the division of 91809106 by 52 
We're looking to find how many times 52 goes into 91809106.

On to step 1:
52 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 52

Let's proceed to step 2:
If we divide 91 by 52, we get 1 and a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 52 from 91 leaves us with 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 52

Step 3:
52 can be fit into 398 7 times, resulting in a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 364 from 398, we get 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 52

Going ahead to step 4:
If we divide 340 by 52, we get 6 and a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 176.0
Subtracting 312 from 340 leaves us with 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 52

Step 5:
The number 52 fits into 289 5 times, leaving a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 1765.0
Subtracting 260 from 289 leaves us with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 52

Let's proceed to step 6:
52 goes into 291 5 times with a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 17655.0
Subtract 260 from 291 to get 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 52

Advancing to step 7:
52 can be fit into 310 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 176555.0
The remainder is 50 after subtracting 260 from 310.
Include the next digit (6) from the dividend after 50, then repeat: 506 / 52

On to step 8:
506 divided by 52 is 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 1765559.0
Subtracting 468 from 506 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
52 goes into 380 7 times with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 1765559.7
The remainder is 16 after subtracting 364 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
The number 52 fits into 160 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 1765559.73
Subtracting 156 from 160 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.

Let's proceed to step 11:
40 divided by 52 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1765559.73
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
52 can be fit into 400 7 times, resulting in a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 1765559.7307
Subtracting 364 from 400 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
If we divide 360 by 52, we get 6 and a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 1765559.73076
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
The number 52 fits into 480 9 times, leaving a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 1765559.730769
Deduct 468 from 480 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 15:
When dividing 120 by 52, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 1765559.7307692
The remainder is 16 after subtracting 104 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 16:
When dividing 160 by 52, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 1765559.73076923
Deduct 156 from 160 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 1765559.73076923 with a remainder of 4e-09.
