405801 ÷ 52 
We want to figure out the number of times 405801 can be divided by 52.

Step 1:
4 divided by 52 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 52

Let's proceed to step 2:
40 divided by 52 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 52

On to step 3:
The number 52 fits into 405 7 times, leaving a remainder of 41.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 364 from 405 and we're left with 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 52

Advancing to step 4:
52 goes into 418 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtract 416 from 418 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 52

On to step 5:
52 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 780.0
Subtracting 0 from 20 leaves us with 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 52

Let's proceed to step 6:
The number 52 fits into 201 3 times, leaving a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 7803.0
Deduct 156 from 201 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
52 can be fit into 450 8 times, resulting in a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 7803.8
Subtract 416 from 450 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
When dividing 340 by 52, we get 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 7803.86
If we subtract 312 from 340, we 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.

Advancing to step 9:
280 divided by 52 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 7803.865
If we take 260 away from 280, we end up 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.

Moving on to step 10:
If we divide 200 by 52, we get 3 and a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 7803.8653
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
If we divide 440 by 52, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 7803.86538
The remainder is 24 after subtracting 416 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
The number 52 fits into 240 4 times, leaving a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7803.865384
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.

Let's proceed to step 13:
320 divided by 52 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 7803.8653846
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
When dividing 80 by 52, we get 1 with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 7803.86538461
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.

After the division, we end up with 7803.86538461 and a remainder of 2.8e-08.
