We're dividing 42285784 by 109 
We're looking to find how many times 109 goes into 42285784.

Let's proceed to step 1:
The number 109 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 109

On to step 2:
109 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 109

On to step 3:
When dividing 422 by 109, we get 3 with a remainder of 95.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 327 away from 422, we end up with 95.
Append the next digit (8) from the dividend to 95 and continue with: 958 / 109

On to step 4:
If we divide 958 by 109, we get 8 and a remainder of 86.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 872 away from 958, we end up with 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 109

Let's proceed to step 5:
When dividing 865 by 109, we get 7 with a remainder of 102.
Use 7 as the next digit of our solution. 
Result so far: 387.0
The remainder is 102 after subtracting 763 from 865.
Grab the next digit (7) from the dividend, add it to 102, then carry on: 1027 / 109

Let's proceed to step 6:
1027 divided by 109 is 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 3879.0
Subtracting 981 from 1027 leaves us with 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 109

Going ahead to step 7:
468 divided by 109 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 38794.0
Deduct 436 from 468 and we're left with 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 109

On to step 8:
If we divide 324 by 109, we get 2 and a remainder of 106.
Write down 2 as next digit of the result. 
Result so far: 387942.0
If we subtract 218 from 324, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 9:
109 can be fit into 1060 9 times, resulting in a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 387942.9
If we take 981 away from 1060, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 10:
The number 109 fits into 790 7 times, leaving a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 387942.97
Subtract 763 from 790 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 11:
When dividing 270 by 109, we get 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 387942.972
Subtract 218 from 270 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
109 can be fit into 520 4 times, resulting in a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 387942.9724
Subtracting 436 from 520 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 13:
When dividing 840 by 109, we get 7 with a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 387942.97247
If we subtract 763 from 840, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 14:
109 goes into 770 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 387942.972477
Subtract 763 from 770 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 387942.972477 with a remainder of 7e-07.
