We're dividing 10213540 by 407 
We want to divide 10213540 by 407.

Let's proceed to step 1:
If we divide 1 by 407, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 407

Going ahead to step 2:
407 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 407

On to step 3:
407 goes into 102 0 times with a remainder of 102.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 102 and we're left with 102.
Bring next digit (1) of the dividend behind the 102 and repeat the process: 1021 / 407

Advancing to step 4:
407 goes into 1021 2 times with a remainder of 207.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 207 after subtracting 814 from 1021.
Append the next digit (3) from the dividend to 207 and continue with: 2073 / 407

On to step 5:
407 can be fit into 2073 5 times, resulting in a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 2035 from 2073 leaves us with 38.
Grab the next digit (5) from the dividend, add it to 38, then carry on: 385 / 407

Step 6:
The number 407 fits into 385 0 times, leaving a remainder of 385.
Put 0 as the next digit of the answer. 
Result so far: 250.0
Subtracting 0 from 385 leaves us with 385.
Fetch the next digit (4) from the dividend, attach it to 385 and continue: 3854 / 407

Going ahead to step 7:
The number 407 fits into 3854 9 times, leaving a remainder of 191.
Put 9 as the next digit of the answer. 
Result so far: 2509.0
Subtract 3663 from 3854 to get 191.
Take the next digit (0) from the dividend and append it to 191, then repeat: 1910 / 407

Moving on to step 8:
407 goes into 1910 4 times with a remainder of 282.
Record the quotient 4 as the next digit in the result. 
Result so far: 25094.0
Deduct 1628 from 1910 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 9:
When dividing 2820 by 407, we get 6 with a remainder of 378.
The number 6 becomes the next digit in our result. 
Result so far: 25094.6
If we subtract 2442 from 2820, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 10:
If we divide 3780 by 407, we get 9 and a remainder of 117.
The number 9 becomes the next digit in our result. 
Result so far: 25094.69
If we take 3663 away from 3780, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 11:
If we divide 1170 by 407, we get 2 and a remainder of 356.
Put 2 as the next digit of the answer. 
Result so far: 25094.692
Subtract 814 from 1170 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 12:
If we divide 3560 by 407, we get 8 and a remainder of 304.
Record the quotient 8 as the next digit in the result. 
Result so far: 25094.6928
If we take 3256 away from 3560, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 13:
The number 407 fits into 3040 7 times, leaving a remainder of 191.
The next digit of our result is 7. 
Result so far: 25094.69287
Subtracting 2849 from 3040 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 14:
The number 407 fits into 1910 4 times, leaving a remainder of 282.
The number 4 becomes the next digit in our result. 
Result so far: 25094.692874
If we take 1628 away from 1910, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 15:
If we divide 2820 by 407, we get 6 and a remainder of 378.
Put 6 as the next digit of the answer. 
Result so far: 25094.6928746
If we take 2442 away from 2820, we end up with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 16:
407 goes into 3780 9 times with a remainder of 117.
The number 9 becomes the next digit in our result. 
Result so far: 25094.69287469
Subtract 3663 from 3780 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

After the division, we end up with 25094.69287469 and a remainder of 1.17e-07.
