We look at the division of 12589442 by 738 
We want to divide 12589442 by 738.

Advancing to step 1:
738 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 738

Let's proceed to step 2:
738 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 738

Going ahead to step 3:
The number 738 fits into 125 0 times, leaving a remainder of 125.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 125 after subtracting 0 from 125.
Include the next digit (8) from the dividend after 125, then repeat: 1258 / 738

Step 4:
If we divide 1258 by 738, we get 1 and a remainder of 520.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 738 from 1258 leaves us with 520.
Include the next digit (9) from the dividend after 520, then repeat: 5209 / 738

Going ahead to step 5:
738 goes into 5209 7 times with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 5166 from 5209 leaves us with 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 738

On to step 6:
738 goes into 434 0 times with a remainder of 434.
Use 0 as the next digit of our solution. 
Result so far: 170.0
The remainder is 434 after subtracting 0 from 434.
Append the next digit (4) from the dividend to 434 and continue with: 4344 / 738

Let's proceed to step 7:
4344 divided by 738 is 5 with a remainder of 654.
Write down 5 as next digit of the result. 
Result so far: 1705.0
If we take 3690 away from 4344, we end up with 654.
Grab the next digit (2) from the dividend, add it to 654, then carry on: 6542 / 738

Step 8:
The number 738 fits into 6542 8 times, leaving a remainder of 638.
Record the quotient 8 as the next digit in the result. 
Result so far: 17058.0
Subtract 5904 from 6542 to get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Advancing to step 9:
The number 738 fits into 6380 8 times, leaving a remainder of 476.
Record the quotient 8 as the next digit in the result. 
Result so far: 17058.8
If we take 5904 away from 6380, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Advancing to step 10:
738 goes into 4760 6 times with a remainder of 332.
Put 6 as the next digit of the answer. 
Result so far: 17058.86
If we subtract 4428 from 4760, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 11:
3320 divided by 738 is 4 with a remainder of 368.
Use 4 as the next digit of our solution. 
Result so far: 17058.864
Subtract 2952 from 3320 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 12:
738 goes into 3680 4 times with a remainder of 728.
The number 4 becomes the next digit in our result. 
Result so far: 17058.8644
If we take 2952 away from 3680, we end up with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

After the division, we end up with 17058.8644 and a remainder of 0.00728.
