42588010 divided by 305 
We want to figure out the number of times 42588010 can be divided by 305.

Going ahead to step 1:
305 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 305

On to step 2:
305 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 305

Step 3:
The number 305 fits into 425 1 times, leaving a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 120 after subtracting 305 from 425.
Include the next digit (8) from the dividend after 120, then repeat: 1208 / 305

Step 4:
When dividing 1208 by 305, we get 3 with a remainder of 293.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 915 away from 1208, we end up with 293.
Fetch the next digit (8) from the dividend, attach it to 293 and continue: 2938 / 305

Going ahead to step 5:
If we divide 2938 by 305, we get 9 and a remainder of 193.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
Subtract 2745 from 2938 to get 193.
Fetch the next digit (0) from the dividend, attach it to 193 and continue: 1930 / 305

Let's proceed to step 6:
305 goes into 1930 6 times with a remainder of 100.
Record the quotient 6 as the next digit in the result. 
Result so far: 1396.0
Deduct 1830 from 1930 and we're left with 100.
Include the next digit (1) from the dividend after 100, then repeat: 1001 / 305

Step 7:
305 can be fit into 1001 3 times, resulting in a remainder of 86.
The number 3 becomes the next digit in our result. 
Result so far: 13963.0
The remainder is 86 after subtracting 915 from 1001.
Take the next digit (0) from the dividend and append it to 86, then repeat: 860 / 305

Moving on to step 8:
The number 305 fits into 860 2 times, leaving a remainder of 250.
Put 2 as the next digit of the answer. 
Result so far: 139632.0
The remainder is 250 after subtracting 610 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 9:
If we divide 2500 by 305, we get 8 and a remainder of 60.
The next digit of our result is 8. 
Result so far: 139632.8
Subtracting 2440 from 2500 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
305 goes into 600 1 times with a remainder of 295.
Use 1 as the next digit of our solution. 
Result so far: 139632.81
Deduct 305 from 600 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 11:
If we divide 2950 by 305, we get 9 and a remainder of 205.
Use 9 as the next digit of our solution. 
Result so far: 139632.819
Subtract 2745 from 2950 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 12:
When dividing 2050 by 305, we get 6 with a remainder of 220.
Record the quotient 6 as the next digit in the result. 
Result so far: 139632.8196
Subtract 1830 from 2050 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 13:
305 goes into 2200 7 times with a remainder of 65.
The next digit of our result is 7. 
Result so far: 139632.81967
Deduct 2135 from 2200 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 14:
305 goes into 650 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 139632.819672
If we subtract 610 from 650, 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.

On to step 15:
The number 305 fits into 400 1 times, leaving a remainder of 95.
Use 1 as the next digit of our solution. 
Result so far: 139632.8196721
Deduct 305 from 400 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 16:
305 can be fit into 950 3 times, resulting in a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 139632.81967213
The remainder is 35 after subtracting 915 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 139632.81967213 with a remainder of 3.5e-08.
