42145086 divided by 109 
Let's see how many times 109 fits into 42145086.

Let's proceed to step 1:
The number 109 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 109

Moving on to step 2:
109 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 109

Moving on to step 3:
If we divide 421 by 109, we get 3 and a remainder of 94.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 327 from 421 leaves us with 94.
Include the next digit (4) from the dividend after 94, then repeat: 944 / 109

Advancing to step 4:
The number 109 fits into 944 8 times, leaving a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
The remainder is 72 after subtracting 872 from 944.
Append the next digit (5) from the dividend to 72 and continue with: 725 / 109

Let's proceed to step 5:
When dividing 725 by 109, we get 6 with a remainder of 71.
Use 6 as the next digit of our solution. 
Result so far: 386.0
If we take 654 away from 725, we end up with 71.
Include the next digit (0) from the dividend after 71, then repeat: 710 / 109

Moving on to step 6:
If we divide 710 by 109, we get 6 and a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 3866.0
Subtracting 654 from 710 leaves us with 56.
Include the next digit (8) from the dividend after 56, then repeat: 568 / 109

Moving on to step 7:
When dividing 568 by 109, we get 5 with a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 38665.0
If we subtract 545 from 568, we get 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 109

Moving on to step 8:
The number 109 fits into 236 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 386652.0
If we subtract 218 from 236, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
109 can be fit into 180 1 times, resulting in a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 386652.1
Subtracting 109 from 180 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 10:
If we divide 710 by 109, we get 6 and a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 386652.16
If we take 654 away from 710, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
If we divide 560 by 109, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 386652.165
If we take 545 away from 560, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
150 divided by 109 is 1 with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 386652.1651
If we subtract 109 from 150, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 13:
The number 109 fits into 410 3 times, leaving a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 386652.16513
Subtracting 327 from 410 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 14:
If we divide 830 by 109, we get 7 and a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 386652.165137
If we subtract 763 from 830, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 15:
The number 109 fits into 670 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 386652.1651376
Deduct 654 from 670 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 16:
When dividing 160 by 109, we get 1 with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 386652.16513761
The remainder is 51 after subtracting 109 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 386652.16513761 with a remainder of 5.1e-08.
