We're dividing 87139086 by 52 
We're looking to find how many times 52 goes into 87139086.

Let's proceed to 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
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 52

Advancing to step 2:
When dividing 87 by 52, we get 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 52 from 87 and we're left with 35.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 52

Advancing to step 3:
The number 52 fits into 351 6 times, leaving a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 312 from 351 and we're left with 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 52

Going ahead to step 4:
52 can be fit into 393 7 times, resulting in a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
The remainder is 29 after subtracting 364 from 393.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 52

Step 5:
If we divide 299 by 52, we get 5 and a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 1675.0
The remainder is 39 after subtracting 260 from 299.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 52

Going ahead to step 6:
If we divide 390 by 52, we get 7 and a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 16757.0
The remainder is 26 after subtracting 364 from 390.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 52

Moving on to step 7:
When dividing 268 by 52, we get 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 167575.0
Subtract 260 from 268 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 52

Advancing to step 8:
52 goes into 86 1 times with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1675751.0
Deduct 52 from 86 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
52 goes into 340 6 times with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 1675751.6
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
If we divide 280 by 52, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 1675751.65
Subtracting 260 from 280 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
52 goes into 200 3 times with a remainder of 44.
The next digit of our result is 3. 
Result so far: 1675751.653
If we take 156 away from 200, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
The number 52 fits into 440 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 1675751.6538
If we subtract 416 from 440, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
240 divided by 52 is 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 1675751.65384
The remainder is 32 after subtracting 208 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
52 can be fit into 320 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1675751.653846
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 15:
80 divided by 52 is 1 with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1675751.6538461
Subtracting 52 from 80 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 16:
52 goes into 280 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1675751.65384615
Subtracting 260 from 280 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 1675751.65384615 with a remainder of 2e-08.
