We're dividing 42428236 by 964 
Let's see how many times 964 fits into 42428236.

Advancing to step 1:
The number 964 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 964

Advancing to step 2:
When dividing 42 by 964, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 964

On to step 3:
964 can be fit into 424 0 times, resulting in a remainder of 424.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 424 and we're left with 424.
Append the next digit (2) from the dividend to 424 and continue with: 4242 / 964

Advancing to step 4:
964 goes into 4242 4 times with a remainder of 386.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3856 from 4242, we get 386.
Bring next digit (8) of the dividend behind the 386 and repeat the process: 3868 / 964

Step 5:
964 goes into 3868 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtracting 3856 from 3868 leaves us with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 964

On to step 6:
964 can be fit into 122 0 times, resulting in a remainder of 122.
The next digit of our result is 0. 
Result so far: 440.0
If we subtract 0 from 122, we get 122.
Grab the next digit (3) from the dividend, add it to 122, then carry on: 1223 / 964

Step 7:
964 can be fit into 1223 1 times, resulting in a remainder of 259.
Write down 1 as next digit of the result. 
Result so far: 4401.0
Subtracting 964 from 1223 leaves us with 259.
Append the next digit (6) from the dividend to 259 and continue with: 2596 / 964

Step 8:
964 goes into 2596 2 times with a remainder of 668.
The next digit of our result is 2. 
Result so far: 44012.0
If we take 1928 away from 2596, we end up with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Advancing to step 9:
When dividing 6680 by 964, we get 6 with a remainder of 896.
The next digit of our result is 6. 
Result so far: 44012.6
If we subtract 5784 from 6680, we get 896.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8960, and continue the process.

Step 10:
964 goes into 8960 9 times with a remainder of 284.
Record the quotient 9 as the next digit in the result. 
Result so far: 44012.69
Deduct 8676 from 8960 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 11:
964 can be fit into 2840 2 times, resulting in a remainder of 912.
Record the quotient 2 as the next digit in the result. 
Result so far: 44012.692
The remainder is 912 after subtracting 1928 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9120, and continue the process.

Going ahead to step 12:
964 goes into 9120 9 times with a remainder of 444.
Write down 9 as next digit of the result. 
Result so far: 44012.6929
If we take 8676 away from 9120, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 13:
4440 divided by 964 is 4 with a remainder of 584.
Use 4 as the next digit of our solution. 
Result so far: 44012.69294
The remainder is 584 after subtracting 3856 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Advancing to step 14:
964 goes into 5840 6 times with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 44012.692946
If we subtract 5784 from 5840, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 15:
When dividing 560 by 964, we get 0 with a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 44012.692946
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 16:
If we divide 5600 by 964, we get 5 and a remainder of 780.
Put 5 as the next digit of the answer. 
Result so far: 44012.69294605
Subtracting 4820 from 5600 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

The final outcome is 44012.69294605, with a leftover of 7.8e-07.
