40102 ÷ 52 
We want to figure out the number of times 40102 can be divided by 52.

Step 1:
If we divide 4 by 52, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 52

Step 2:
The number 52 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 52

Moving on to step 3:
The number 52 fits into 401 7 times, leaving a remainder of 37.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 364 from 401 and we're left with 37.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 52

Moving on to step 4:
When dividing 370 by 52, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Subtracting 364 from 370 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 52

Let's proceed to step 5:
52 can be fit into 62 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 771.0
Subtracting 52 from 62 leaves us 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.

Going ahead to step 6:
52 can be fit into 100 1 times, resulting in a remainder of 48.
The next digit of our result is 1. 
Result so far: 771.1
The remainder is 48 after subtracting 52 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
480 divided by 52 is 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 771.19
The remainder is 12 after subtracting 468 from 480.
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 8:
52 goes into 120 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 771.192
Subtracting 104 from 120 leaves us 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.

On to step 9:
When dividing 160 by 52, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 771.1923
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.

Moving on to step 10:
40 divided by 52 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 771.1923
Subtract 0 from 40 to 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 11:
52 can be fit into 400 7 times, resulting in a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 771.192307
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 12:
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: 771.1923076
Subtract 312 from 360 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.

Let's proceed to step 13:
When dividing 480 by 52, we get 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 771.19230769
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 771.19230769 with a remainder of 1.2e-08.
