We're dividing 52406593 by 387 
We want to figure out the number of times 52406593 can be divided by 387.

Moving on to step 1:
387 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 387

Let's proceed to step 2:
When dividing 52 by 387, we get 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 387

Step 3:
387 can be fit into 524 1 times, resulting in a remainder of 137.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 387 from 524 to get 137.
Bring next digit (0) of the dividend behind the 137 and repeat the process: 1370 / 387

Step 4:
When dividing 1370 by 387, we get 3 with a remainder of 209.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 1161 from 1370 to get 209.
Fetch the next digit (6) from the dividend, attach it to 209 and continue: 2096 / 387

Going ahead to step 5:
2096 divided by 387 is 5 with a remainder of 161.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
If we subtract 1935 from 2096, we get 161.
Bring next digit (5) of the dividend behind the 161 and repeat the process: 1615 / 387

Going ahead to step 6:
The number 387 fits into 1615 4 times, leaving a remainder of 67.
Record the quotient 4 as the next digit in the result. 
Result so far: 1354.0
Subtracting 1548 from 1615 leaves us with 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 387

Advancing to step 7:
If we divide 679 by 387, we get 1 and a remainder of 292.
Record the quotient 1 as the next digit in the result. 
Result so far: 13541.0
If we subtract 387 from 679, we get 292.
Append the next digit (3) from the dividend to 292 and continue with: 2923 / 387

Moving on to step 8:
387 goes into 2923 7 times with a remainder of 214.
Put 7 as the next digit of the answer. 
Result so far: 135417.0
If we take 2709 away from 2923, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 9:
The number 387 fits into 2140 5 times, leaving a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 135417.5
Subtracting 1935 from 2140 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 10:
387 goes into 2050 5 times with a remainder of 115.
The next digit of our result is 5. 
Result so far: 135417.55
The remainder is 115 after subtracting 1935 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Our division results in 135417.55 with a remaining 0.115.
