We're dividing 16513718 by 407 
Our goal is to divide 16513718 by 407.

Moving on to step 1:
The number 407 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 407

Let's proceed to step 2:
If we divide 16 by 407, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 407

Let's proceed to step 3:
165 divided by 407 is 0 with a remainder of 165.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 165 and we're left with 165.
Fetch the next digit (1) from the dividend, attach it to 165 and continue: 1651 / 407

On to step 4:
407 goes into 1651 4 times with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 1628 from 1651, we get 23.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 407

On to step 5:
233 divided by 407 is 0 with a remainder of 233.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 233, we end up with 233.
Take the next digit (7) from the dividend and append it to 233, then repeat: 2337 / 407

Advancing to step 6:
The number 407 fits into 2337 5 times, leaving a remainder of 302.
Record the quotient 5 as the next digit in the result. 
Result so far: 405.0
If we take 2035 away from 2337, we end up with 302.
Take the next digit (1) from the dividend and append it to 302, then repeat: 3021 / 407

Let's proceed to step 7:
When dividing 3021 by 407, we get 7 with a remainder of 172.
Use 7 as the next digit of our solution. 
Result so far: 4057.0
Deduct 2849 from 3021 and we're left with 172.
Include the next digit (8) from the dividend after 172, then repeat: 1728 / 407

Let's proceed to step 8:
1728 divided by 407 is 4 with a remainder of 100.
The number 4 becomes the next digit in our result. 
Result so far: 40574.0
The remainder is 100 after subtracting 1628 from 1728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 9:
When dividing 1000 by 407, we get 2 with a remainder of 186.
Write down 2 as next digit of the result. 
Result so far: 40574.2
If we take 814 away from 1000, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 10:
The number 407 fits into 1860 4 times, leaving a remainder of 232.
Record the quotient 4 as the next digit in the result. 
Result so far: 40574.24
Deduct 1628 from 1860 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 11:
The number 407 fits into 2320 5 times, leaving a remainder of 285.
The number 5 becomes the next digit in our result. 
Result so far: 40574.245
If we subtract 2035 from 2320, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 12:
407 can be fit into 2850 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 40574.2457
If we take 2849 away from 2850, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
The number 407 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 40574.2457
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
407 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 40574.2457
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 40574.2457, with a leftover of 1e-05.
