We're dividing 42507321 by 905 
We're looking to find how many times 905 goes into 42507321.

On to step 1:
905 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 905

Moving on to step 2:
When dividing 42 by 905, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 905

Step 3:
The number 905 fits into 425 0 times, leaving a remainder of 425.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 425 leaves us with 425.
Fetch the next digit (0) from the dividend, attach it to 425 and continue: 4250 / 905

Step 4:
If we divide 4250 by 905, we get 4 and a remainder of 630.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 3620 from 4250 leaves us with 630.
Bring next digit (7) of the dividend behind the 630 and repeat the process: 6307 / 905

On to step 5:
The number 905 fits into 6307 6 times, leaving a remainder of 877.
Write down 6 as next digit of the result. 
Result so far: 46.0
The remainder is 877 after subtracting 5430 from 6307.
Include the next digit (3) from the dividend after 877, then repeat: 8773 / 905

Step 6:
905 goes into 8773 9 times with a remainder of 628.
The next digit of our result is 9. 
Result so far: 469.0
The remainder is 628 after subtracting 8145 from 8773.
Include the next digit (2) from the dividend after 628, then repeat: 6282 / 905

Advancing to step 7:
The number 905 fits into 6282 6 times, leaving a remainder of 852.
The number 6 becomes the next digit in our result. 
Result so far: 4696.0
Deduct 5430 from 6282 and we're left with 852.
Bring next digit (1) of the dividend behind the 852 and repeat the process: 8521 / 905

Let's proceed to step 8:
When dividing 8521 by 905, we get 9 with a remainder of 376.
Use 9 as the next digit of our solution. 
Result so far: 46969.0
The remainder is 376 after subtracting 8145 from 8521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 9:
905 goes into 3760 4 times with a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 46969.4
Subtract 3620 from 3760 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 10:
1400 divided by 905 is 1 with a remainder of 495.
Record the quotient 1 as the next digit in the result. 
Result so far: 46969.41
Subtracting 905 from 1400 leaves us with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Going ahead to step 11:
905 goes into 4950 5 times with a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 46969.415
Deduct 4525 from 4950 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 12:
905 can be fit into 4250 4 times, resulting in a remainder of 630.
Record the quotient 4 as the next digit in the result. 
Result so far: 46969.4154
If we subtract 3620 from 4250, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 13:
905 can be fit into 6300 6 times, resulting in a remainder of 870.
Record the quotient 6 as the next digit in the result. 
Result so far: 46969.41546
If we subtract 5430 from 6300, we get 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

Step 14:
905 can be fit into 8700 9 times, resulting in a remainder of 555.
The number 9 becomes the next digit in our result. 
Result so far: 46969.415469
If we subtract 8145 from 8700, we get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Going ahead to step 15:
905 can be fit into 5550 6 times, resulting in a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 46969.4154696
The remainder is 120 after subtracting 5430 from 5550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 16:
905 can be fit into 1200 1 times, resulting in a remainder of 295.
The number 1 becomes the next digit in our result. 
Result so far: 46969.41546961
Subtracting 905 from 1200 leaves us 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.

After the division, we end up with 46969.41546961 and a remainder of 2.95e-07.
