42615901 ÷ 389 
Let's see how many times 389 fits into 42615901.

Step 1:
The number 389 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 389

Going ahead to step 2:
42 divided by 389 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 389

Moving on to step 3:
If we divide 426 by 389, we get 1 and a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 389 from 426, we get 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 389

On to step 4:
The number 389 fits into 371 0 times, leaving a remainder of 371.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 371, we get 371.
Fetch the next digit (5) from the dividend, attach it to 371 and continue: 3715 / 389

Going ahead to step 5:
The number 389 fits into 3715 9 times, leaving a remainder of 214.
Use 9 as the next digit of our solution. 
Result so far: 109.0
If we take 3501 away from 3715, we end up with 214.
Fetch the next digit (9) from the dividend, attach it to 214 and continue: 2149 / 389

On to step 6:
The number 389 fits into 2149 5 times, leaving a remainder of 204.
The number 5 becomes the next digit in our result. 
Result so far: 1095.0
Subtracting 1945 from 2149 leaves us with 204.
Append the next digit (0) from the dividend to 204 and continue with: 2040 / 389

Let's proceed to step 7:
When dividing 2040 by 389, we get 5 with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 10955.0
Subtracting 1945 from 2040 leaves us with 95.
Grab the next digit (1) from the dividend, add it to 95, then carry on: 951 / 389

On to step 8:
If we divide 951 by 389, we get 2 and a remainder of 173.
The next digit of our result is 2. 
Result so far: 109552.0
Deduct 778 from 951 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 9:
389 goes into 1730 4 times with a remainder of 174.
The next digit of our result is 4. 
Result so far: 109552.4
If we subtract 1556 from 1730, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 10:
The number 389 fits into 1740 4 times, leaving a remainder of 184.
Record the quotient 4 as the next digit in the result. 
Result so far: 109552.44
The remainder is 184 after subtracting 1556 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final outcome is 109552.44, with a leftover of 0.184.
