We're dividing 12434590 by 940 
Let's see how many times 940 fits into 12434590.

Moving on to step 1:
1 divided by 940 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 940

Let's proceed to step 2:
940 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
The remainder is 12 after subtracting 0 from 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 940

Let's proceed to step 3:
124 divided by 940 is 0 with a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 124, we end up with 124.
Bring next digit (3) of the dividend behind the 124 and repeat the process: 1243 / 940

Advancing to step 4:
940 can be fit into 1243 1 times, resulting in a remainder of 303.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 940 from 1243 to get 303.
Grab the next digit (4) from the dividend, add it to 303, then carry on: 3034 / 940

On to step 5:
If we divide 3034 by 940, we get 3 and a remainder of 214.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 214 after subtracting 2820 from 3034.
Take the next digit (5) from the dividend and append it to 214, then repeat: 2145 / 940

Let's proceed to step 6:
940 goes into 2145 2 times with a remainder of 265.
Use 2 as the next digit of our solution. 
Result so far: 132.0
Subtract 1880 from 2145 to get 265.
Take the next digit (9) from the dividend and append it to 265, then repeat: 2659 / 940

Moving on to step 7:
940 goes into 2659 2 times with a remainder of 779.
Put 2 as the next digit of the answer. 
Result so far: 1322.0
The remainder is 779 after subtracting 1880 from 2659.
Bring next digit (0) of the dividend behind the 779 and repeat the process: 7790 / 940

On to step 8:
7790 divided by 940 is 8 with a remainder of 270.
The number 8 becomes the next digit in our result. 
Result so far: 13228.0
Subtract 7520 from 7790 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 9:
2700 divided by 940 is 2 with a remainder of 820.
The next digit of our result is 2. 
Result so far: 13228.2
If we take 1880 away from 2700, we end up with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Step 10:
940 can be fit into 8200 8 times, resulting in a remainder of 680.
Use 8 as the next digit of our solution. 
Result so far: 13228.28
Deduct 7520 from 8200 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 11:
If we divide 6800 by 940, we get 7 and a remainder of 220.
Put 7 as the next digit of the answer. 
Result so far: 13228.287
Deduct 6580 from 6800 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 12:
940 goes into 2200 2 times with a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 13228.2872
If we take 1880 away from 2200, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 13:
940 goes into 3200 3 times with a remainder of 380.
Write down 3 as next digit of the result. 
Result so far: 13228.28723
Subtracting 2820 from 3200 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 14:
940 goes into 3800 4 times with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 13228.287234
The remainder is 40 after subtracting 3760 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 15:
940 can be fit into 400 0 times, resulting in a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 13228.287234
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 16:
When dividing 4000 by 940, we get 4 with a remainder of 240.
The next digit of our result is 4. 
Result so far: 13228.28723404
Deduct 3760 from 4000 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final outcome is 13228.28723404, with a leftover of 2.4e-07.
