We look at the division of 40124210 by 783 
Our goal is to divide 40124210 by 783.

Advancing to step 1:
The number 783 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
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 783

Step 2:
783 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 783

Step 3:
When dividing 401 by 783, we get 0 with a remainder of 401.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 401, we end up with 401.
Bring next digit (2) of the dividend behind the 401 and repeat the process: 4012 / 783

Moving on to step 4:
The number 783 fits into 4012 5 times, leaving a remainder of 97.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 3915 from 4012 leaves us with 97.
Grab the next digit (4) from the dividend, add it to 97, then carry on: 974 / 783

Going ahead to step 5:
783 goes into 974 1 times with a remainder of 191.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we take 783 away from 974, we end up with 191.
Bring next digit (2) of the dividend behind the 191 and repeat the process: 1912 / 783

Step 6:
If we divide 1912 by 783, we get 2 and a remainder of 346.
Use 2 as the next digit of our solution. 
Result so far: 512.0
Subtract 1566 from 1912 to get 346.
Include the next digit (1) from the dividend after 346, then repeat: 3461 / 783

Going ahead to step 7:
If we divide 3461 by 783, we get 4 and a remainder of 329.
Record the quotient 4 as the next digit in the result. 
Result so far: 5124.0
Deduct 3132 from 3461 and we're left with 329.
Bring next digit (0) of the dividend behind the 329 and repeat the process: 3290 / 783

Let's proceed to step 8:
783 goes into 3290 4 times with a remainder of 158.
Record the quotient 4 as the next digit in the result. 
Result so far: 51244.0
If we subtract 3132 from 3290, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 9:
783 goes into 1580 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 51244.2
Deduct 1566 from 1580 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
The number 783 fits into 140 0 times, leaving a remainder of 140.
The next digit of our result is 0. 
Result so far: 51244.2
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
783 goes into 1400 1 times with a remainder of 617.
Write down 1 as next digit of the result. 
Result so far: 51244.201
If we subtract 783 from 1400, we get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Moving on to step 12:
783 goes into 6170 7 times with a remainder of 689.
The number 7 becomes the next digit in our result. 
Result so far: 51244.2017
The remainder is 689 after subtracting 5481 from 6170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Advancing to step 13:
783 can be fit into 6890 8 times, resulting in a remainder of 626.
Write down 8 as next digit of the result. 
Result so far: 51244.20178
Subtract 6264 from 6890 to get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Moving on to step 14:
783 goes into 6260 7 times with a remainder of 779.
The number 7 becomes the next digit in our result. 
Result so far: 51244.201787
The remainder is 779 after subtracting 5481 from 6260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

Moving on to step 15:
783 goes into 7790 9 times with a remainder of 743.
Record the quotient 9 as the next digit in the result. 
Result so far: 51244.2017879
Deduct 7047 from 7790 and we're left with 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Moving on to step 16:
783 can be fit into 7430 9 times, resulting in a remainder of 383.
The number 9 becomes the next digit in our result. 
Result so far: 51244.20178799
The remainder is 383 after subtracting 7047 from 7430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Our division results in 51244.20178799 with a remaining 3.83e-07.
