We divide 81669286 by 52
We want to figure out the number of times 81669286 can be divided by 52.

Step 1:
If we divide 8 by 52, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 52

Advancing to step 2:
If we divide 81 by 52, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 52 away from 81, we end up with 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 52

Let's proceed to step 3:
The number 52 fits into 296 5 times, leaving a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 260 away from 296, we end up with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 52

Advancing to step 4:
52 can be fit into 366 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 157.0
Subtract 364 from 366 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 52

On to step 5:
The number 52 fits into 29 0 times, leaving a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 1570.0
Deduct 0 from 29 and we're left with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 52

On to step 6:
292 divided by 52 is 5 with a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 15705.0
If we subtract 260 from 292, we get 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 52

Let's proceed to step 7:
The number 52 fits into 328 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 157056.0
Subtract 312 from 328 to get 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 52

Let's proceed to step 8:
The number 52 fits into 166 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 1570563.0
Deduct 156 from 166 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 52, we get 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 1570563.1
Subtract 52 from 100 to 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.

Moving on to step 10:
If we divide 480 by 52, we get 9 and a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 1570563.19
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.

Moving on to step 11:
52 can be fit into 120 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 1570563.192
If we take 104 away from 120, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
52 goes into 160 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 1570563.1923
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
The number 52 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1570563.1923
If we subtract 0 from 40, we get 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 14:
52 goes into 400 7 times with a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 1570563.192307
If we take 364 away from 400, we end up 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.

Let's proceed to step 15:
If we divide 360 by 52, we get 6 and a remainder of 48.
The next digit of our result is 6. 
Result so far: 1570563.1923076
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 16:
52 can be fit into 480 9 times, resulting in a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 1570563.19230769
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 1570563.19230769 with a remaining 1.2e-08.
