42909209 divided by 860 
We want to figure out the number of times 42909209 can be divided by 860.

Advancing to step 1:
When dividing 4 by 860, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 860

Moving on to step 2:
If we divide 42 by 860, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 860

On to step 3:
The number 860 fits into 429 0 times, leaving a remainder of 429.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 429, we end up with 429.
Grab the next digit (0) from the dividend, add it to 429, then carry on: 4290 / 860

Moving on to step 4:
If we divide 4290 by 860, we get 4 and a remainder of 850.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 3440 from 4290 leaves us with 850.
Bring next digit (9) of the dividend behind the 850 and repeat the process: 8509 / 860

Step 5:
The number 860 fits into 8509 9 times, leaving a remainder of 769.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we subtract 7740 from 8509, we get 769.
Append the next digit (2) from the dividend to 769 and continue with: 7692 / 860

Step 6:
7692 divided by 860 is 8 with a remainder of 812.
Write down 8 as next digit of the result. 
Result so far: 498.0
If we take 6880 away from 7692, we end up with 812.
Bring next digit (0) of the dividend behind the 812 and repeat the process: 8120 / 860

Advancing to step 7:
The number 860 fits into 8120 9 times, leaving a remainder of 380.
Put 9 as the next digit of the answer. 
Result so far: 4989.0
Subtracting 7740 from 8120 leaves us with 380.
Take the next digit (9) from the dividend and append it to 380, then repeat: 3809 / 860

Going ahead to step 8:
If we divide 3809 by 860, we get 4 and a remainder of 369.
Record the quotient 4 as the next digit in the result. 
Result so far: 49894.0
If we take 3440 away from 3809, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Going ahead to step 9:
The number 860 fits into 3690 4 times, leaving a remainder of 250.
Record the quotient 4 as the next digit in the result. 
Result so far: 49894.4
If we subtract 3440 from 3690, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 10:
The number 860 fits into 2500 2 times, leaving a remainder of 780.
Use 2 as the next digit of our solution. 
Result so far: 49894.42
If we subtract 1720 from 2500, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

On to step 11:
860 can be fit into 7800 9 times, resulting in a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 49894.429
If we subtract 7740 from 7800, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
The number 860 fits into 600 0 times, leaving a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 49894.429
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 13:
The number 860 fits into 6000 6 times, leaving a remainder of 840.
Write down 6 as next digit of the result. 
Result so far: 49894.42906
Subtract 5160 from 6000 to get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Let's proceed to step 14:
8400 divided by 860 is 9 with a remainder of 660.
The next digit of our result is 9. 
Result so far: 49894.429069
If we subtract 7740 from 8400, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 15:
When dividing 6600 by 860, we get 7 with a remainder of 580.
The number 7 becomes the next digit in our result. 
Result so far: 49894.4290697
The remainder is 580 after subtracting 6020 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 16:
The number 860 fits into 5800 6 times, leaving a remainder of 640.
Put 6 as the next digit of the answer. 
Result so far: 49894.42906976
Subtract 5160 from 5800 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The quotient of the division is 49894.42906976, and the remainder is 6.4e-07.
