Let's divide 72285791 by 406
Our goal is to divide 72285791 by 406.

On to step 1:
406 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 406

Step 2:
72 divided by 406 is 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Append the next digit (2) from the dividend to 72 and continue with: 722 / 406

Moving on to step 3:
The number 406 fits into 722 1 times, leaving a remainder of 316.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 406 from 722 to get 316.
Grab the next digit (8) from the dividend, add it to 316, then carry on: 3168 / 406

Going ahead to step 4:
If we divide 3168 by 406, we get 7 and a remainder of 326.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 2842 from 3168, we get 326.
Fetch the next digit (5) from the dividend, attach it to 326 and continue: 3265 / 406

Moving on to step 5:
The number 406 fits into 3265 8 times, leaving a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 178.0
Deduct 3248 from 3265 and we're left with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 406

Going ahead to step 6:
The number 406 fits into 177 0 times, leaving a remainder of 177.
The next digit of our result is 0. 
Result so far: 1780.0
Deduct 0 from 177 and we're left with 177.
Grab the next digit (9) from the dividend, add it to 177, then carry on: 1779 / 406

Step 7:
406 goes into 1779 4 times with a remainder of 155.
The number 4 becomes the next digit in our result. 
Result so far: 17804.0
Subtract 1624 from 1779 to get 155.
Grab the next digit (1) from the dividend, add it to 155, then carry on: 1551 / 406

Let's proceed to step 8:
406 can be fit into 1551 3 times, resulting in a remainder of 333.
The next digit of our result is 3. 
Result so far: 178043.0
If we take 1218 away from 1551, we end up with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

On to step 9:
The number 406 fits into 3330 8 times, leaving a remainder of 82.
The next digit of our result is 8. 
Result so far: 178043.8
The remainder is 82 after subtracting 3248 from 3330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 10:
406 can be fit into 820 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 178043.82
If we subtract 812 from 820, we 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 11:
When dividing 80 by 406, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 178043.82
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
When dividing 800 by 406, we get 1 with a remainder of 394.
Use 1 as the next digit of our solution. 
Result so far: 178043.8201
If we take 406 away from 800, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 13:
406 can be fit into 3940 9 times, resulting in a remainder of 286.
The next digit of our result is 9. 
Result so far: 178043.82019
The remainder is 286 after subtracting 3654 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 14:
2860 divided by 406 is 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 178043.820197
Deduct 2842 from 2860 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 15:
180 divided by 406 is 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 178043.820197
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 16:
The number 406 fits into 1800 4 times, leaving a remainder of 176.
Record the quotient 4 as the next digit in the result. 
Result so far: 178043.82019704
If we take 1624 away from 1800, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final result is 178043.82019704 with a remainder of 1.76e-07.
