Let's divide 68720784 by 407
We want to divide 68720784 by 407.

Step 1:
6 divided by 407 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 407

Step 2:
407 goes into 68 0 times with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Include the next digit (7) from the dividend after 68, then repeat: 687 / 407

Going ahead to step 3:
When dividing 687 by 407, we get 1 with a remainder of 280.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 280 after subtracting 407 from 687.
Fetch the next digit (2) from the dividend, attach it to 280 and continue: 2802 / 407

Let's proceed to step 4:
2802 divided by 407 is 6 with a remainder of 360.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 2442 from 2802, we get 360.
Grab the next digit (0) from the dividend, add it to 360, then carry on: 3600 / 407

Advancing to step 5:
If we divide 3600 by 407, we get 8 and a remainder of 344.
The next digit of our result is 8. 
Result so far: 168.0
If we take 3256 away from 3600, we end up with 344.
Bring next digit (7) of the dividend behind the 344 and repeat the process: 3447 / 407

On to step 6:
407 can be fit into 3447 8 times, resulting in a remainder of 191.
Write down 8 as next digit of the result. 
Result so far: 1688.0
Deduct 3256 from 3447 and we're left with 191.
Take the next digit (8) from the dividend and append it to 191, then repeat: 1918 / 407

Moving on to step 7:
407 goes into 1918 4 times with a remainder of 290.
Write down 4 as next digit of the result. 
Result so far: 16884.0
Subtract 1628 from 1918 to get 290.
Take the next digit (4) from the dividend and append it to 290, then repeat: 2904 / 407

Advancing to step 8:
When dividing 2904 by 407, we get 7 with a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 168847.0
If we subtract 2849 from 2904, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 9:
If we divide 550 by 407, we get 1 and a remainder of 143.
Record the quotient 1 as the next digit in the result. 
Result so far: 168847.1
Subtracting 407 from 550 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 10:
The number 407 fits into 1430 3 times, leaving a remainder of 209.
Record the quotient 3 as the next digit in the result. 
Result so far: 168847.13
If we take 1221 away from 1430, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 11:
407 can be fit into 2090 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 168847.135
The remainder is 55 after subtracting 2035 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 12:
If we divide 550 by 407, we get 1 and a remainder of 143.
The number 1 becomes the next digit in our result. 
Result so far: 168847.1351
Subtract 407 from 550 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 13:
407 can be fit into 1430 3 times, resulting in a remainder of 209.
Put 3 as the next digit of the answer. 
Result so far: 168847.13513
If we take 1221 away from 1430, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 14:
2090 divided by 407 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 168847.135135
The remainder is 55 after subtracting 2035 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 15:
When dividing 550 by 407, we get 1 with a remainder of 143.
Write down 1 as next digit of the result. 
Result so far: 168847.1351351
If we take 407 away from 550, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 16:
407 can be fit into 1430 3 times, resulting in a remainder of 209.
Use 3 as the next digit of our solution. 
Result so far: 168847.13513513
If we subtract 1221 from 1430, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

The final outcome is 168847.13513513, with a leftover of 2.09e-07.
