72746759 ÷ 407 
We want to figure out the number of times 72746759 can be divided by 407.

Step 1:
The number 407 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 407

Going ahead to step 2:
When dividing 72 by 407, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (7) from the dividend after 72, then repeat: 727 / 407

Moving on to step 3:
When dividing 727 by 407, we get 1 with a remainder of 320.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 407 from 727 to get 320.
Append the next digit (4) from the dividend to 320 and continue with: 3204 / 407

Going ahead to step 4:
407 goes into 3204 7 times with a remainder of 355.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 2849 from 3204, we get 355.
Bring next digit (6) of the dividend behind the 355 and repeat the process: 3556 / 407

Let's proceed to step 5:
If we divide 3556 by 407, we get 8 and a remainder of 300.
The next digit of our result is 8. 
Result so far: 178.0
If we take 3256 away from 3556, we end up with 300.
Grab the next digit (7) from the dividend, add it to 300, then carry on: 3007 / 407

Let's proceed to step 6:
When dividing 3007 by 407, we get 7 with a remainder of 158.
The number 7 becomes the next digit in our result. 
Result so far: 1787.0
Subtract 2849 from 3007 to get 158.
Append the next digit (5) from the dividend to 158 and continue with: 1585 / 407

Moving on to step 7:
When dividing 1585 by 407, we get 3 with a remainder of 364.
The next digit of our result is 3. 
Result so far: 17873.0
If we take 1221 away from 1585, we end up with 364.
Grab the next digit (9) from the dividend, add it to 364, then carry on: 3649 / 407

Let's proceed to step 8:
407 can be fit into 3649 8 times, resulting in a remainder of 393.
Use 8 as the next digit of our solution. 
Result so far: 178738.0
Subtract 3256 from 3649 to get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Going ahead to step 9:
407 can be fit into 3930 9 times, resulting in a remainder of 267.
Use 9 as the next digit of our solution. 
Result so far: 178738.9
The remainder is 267 after subtracting 3663 from 3930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 10:
If we divide 2670 by 407, we get 6 and a remainder of 228.
Record the quotient 6 as the next digit in the result. 
Result so far: 178738.96
If we take 2442 away from 2670, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 11:
The number 407 fits into 2280 5 times, leaving a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 178738.965
The remainder is 245 after subtracting 2035 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 12:
When dividing 2450 by 407, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 178738.9656
Subtract 2442 from 2450 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
407 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 178738.9656
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
407 goes into 800 1 times with a remainder of 393.
Write down 1 as next digit of the result. 
Result so far: 178738.965601
The remainder is 393 after subtracting 407 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Going ahead to step 15:
407 can be fit into 3930 9 times, resulting in a remainder of 267.
Write down 9 as next digit of the result. 
Result so far: 178738.9656019
If we take 3663 away from 3930, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 16:
407 can be fit into 2670 6 times, resulting in a remainder of 228.
The next digit of our result is 6. 
Result so far: 178738.96560196
If we subtract 2442 from 2670, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The final outcome is 178738.96560196, with a leftover of 2.28e-07.
