42190643 divided by 294 
Our goal is to divide 42190643 by 294.

Going ahead to step 1:
4 divided by 294 is 0 with a remainder of 4.
The next digit of our result is 0. 
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 / 294

Let's proceed to step 2:
294 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 294

Advancing to step 3:
When dividing 421 by 294, we get 1 with a remainder of 127.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 294 from 421, we get 127.
Fetch the next digit (9) from the dividend, attach it to 127 and continue: 1279 / 294

Let's proceed to step 4:
294 goes into 1279 4 times with a remainder of 103.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 1176 away from 1279, we end up with 103.
Append the next digit (0) from the dividend to 103 and continue with: 1030 / 294

Let's proceed to step 5:
294 goes into 1030 3 times with a remainder of 148.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
If we subtract 882 from 1030, we get 148.
Bring next digit (6) of the dividend behind the 148 and repeat the process: 1486 / 294

On to step 6:
The number 294 fits into 1486 5 times, leaving a remainder of 16.
The next digit of our result is 5. 
Result so far: 1435.0
If we subtract 1470 from 1486, we get 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 294

Step 7:
The number 294 fits into 164 0 times, leaving a remainder of 164.
Put 0 as the next digit of the answer. 
Result so far: 14350.0
Deduct 0 from 164 and we're left with 164.
Append the next digit (3) from the dividend to 164 and continue with: 1643 / 294

Advancing to step 8:
When dividing 1643 by 294, we get 5 with a remainder of 173.
Use 5 as the next digit of our solution. 
Result so far: 143505.0
Subtract 1470 from 1643 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 9:
If we divide 1730 by 294, we get 5 and a remainder of 260.
Write down 5 as next digit of the result. 
Result so far: 143505.5
The remainder is 260 after subtracting 1470 from 1730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
When dividing 2600 by 294, we get 8 with a remainder of 248.
Use 8 as the next digit of our solution. 
Result so far: 143505.58
Subtract 2352 from 2600 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 11:
2480 divided by 294 is 8 with a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 143505.588
If we take 2352 away from 2480, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 143505.588 with a remainder of 0.0128.
