We look at the division of 42185736 by 109 
We're looking to find how many times 109 goes into 42185736.

Moving on to step 1:
109 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 109

Going ahead to step 2:
42 divided by 109 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 109

On to step 3:
If we divide 421 by 109, we get 3 and a remainder of 94.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 327 from 421 and we're left with 94.
Grab the next digit (8) from the dividend, add it to 94, then carry on: 948 / 109

Advancing to step 4:
When dividing 948 by 109, we get 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 872 from 948, we get 76.
Append the next digit (5) from the dividend to 76 and continue with: 765 / 109

On to step 5:
When dividing 765 by 109, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 387.0
Deduct 763 from 765 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 109

Step 6:
109 goes into 27 0 times with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 3870.0
Subtract 0 from 27 to get 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 109

Advancing to step 7:
If we divide 273 by 109, we get 2 and a remainder of 55.
The next digit of our result is 2. 
Result so far: 38702.0
Subtract 218 from 273 to get 55.
Bring next digit (6) of the dividend behind the 55 and repeat the process: 556 / 109

Going ahead to step 8:
The number 109 fits into 556 5 times, leaving a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 387025.0
Subtract 545 from 556 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
109 goes into 110 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 387025.1
The remainder is 1 after subtracting 109 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
If we divide 10 by 109, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 387025.1
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
When dividing 100 by 109, we get 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 387025.1
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 387025.1 with a balance of 0.01.
