42546643 divided by 109 
We're looking to find how many times 109 goes into 42546643.

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
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 109

Going ahead to step 2:
109 can be fit into 42 0 times, resulting in 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.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 109

Step 3:
If we divide 425 by 109, we get 3 and a remainder of 98.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 327 from 425 to get 98.
Bring next digit (4) of the dividend behind the 98 and repeat the process: 984 / 109

On to step 4:
109 can be fit into 984 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 39.0
The remainder is 3 after subtracting 981 from 984.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 109

On to step 5:
If we divide 36 by 109, we get 0 and a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 390.0
If we subtract 0 from 36, we get 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 109

On to step 6:
When dividing 366 by 109, we get 3 with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 3903.0
The remainder is 39 after subtracting 327 from 366.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 109

Advancing to step 7:
The number 109 fits into 394 3 times, leaving a remainder of 67.
The next digit of our result is 3. 
Result so far: 39033.0
If we subtract 327 from 394, we get 67.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 109

Moving on to step 8:
The number 109 fits into 673 6 times, leaving a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 390336.0
Subtracting 654 from 673 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
109 can be fit into 190 1 times, resulting in a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 390336.1
Subtract 109 from 190 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 10:
The number 109 fits into 810 7 times, leaving a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 390336.17
The remainder is 47 after subtracting 763 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 11:
The number 109 fits into 470 4 times, leaving a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 390336.174
The remainder is 34 after subtracting 436 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
109 can be fit into 340 3 times, resulting in a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 390336.1743
If we subtract 327 from 340, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
When dividing 130 by 109, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 390336.17431
The remainder is 21 after subtracting 109 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 14:
If we divide 210 by 109, we get 1 and a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 390336.174311
Deduct 109 from 210 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Our division results in 390336.174311 with a remaining 1.01e-05.
