Let's divide 71939978 by 406
We're looking to find how many times 406 goes into 71939978.

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
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 406

Let's proceed to step 2:
71 divided by 406 is 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 406

Let's proceed to step 3:
The number 406 fits into 719 1 times, leaving a remainder of 313.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 406 from 719 to get 313.
Include the next digit (3) from the dividend after 313, then repeat: 3133 / 406

Let's proceed to step 4:
The number 406 fits into 3133 7 times, leaving a remainder of 291.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 2842 from 3133 leaves us with 291.
Fetch the next digit (9) from the dividend, attach it to 291 and continue: 2919 / 406

Going ahead to step 5:
2919 divided by 406 is 7 with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 177.0
If we take 2842 away from 2919, we end up with 77.
Include the next digit (9) from the dividend after 77, then repeat: 779 / 406

Moving on to step 6:
The number 406 fits into 779 1 times, leaving a remainder of 373.
Use 1 as the next digit of our solution. 
Result so far: 1771.0
Subtract 406 from 779 to get 373.
Bring next digit (7) of the dividend behind the 373 and repeat the process: 3737 / 406

Step 7:
406 goes into 3737 9 times with a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 17719.0
If we take 3654 away from 3737, we end up with 83.
Take the next digit (8) from the dividend and append it to 83, then repeat: 838 / 406

Let's proceed to step 8:
406 goes into 838 2 times with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 177192.0
The remainder is 26 after subtracting 812 from 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
The number 406 fits into 260 0 times, leaving a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 177192.0
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 10:
The number 406 fits into 2600 6 times, leaving a remainder of 164.
The next digit of our result is 6. 
Result so far: 177192.06
Subtracting 2436 from 2600 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 11:
If we divide 1640 by 406, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 177192.064
Subtract 1624 from 1640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
If we divide 160 by 406, we get 0 and a remainder of 160.
The next digit of our result is 0. 
Result so far: 177192.064
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 13:
The number 406 fits into 1600 3 times, leaving a remainder of 382.
The number 3 becomes the next digit in our result. 
Result so far: 177192.06403
Subtract 1218 from 1600 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 14:
406 can be fit into 3820 9 times, resulting in a remainder of 166.
Put 9 as the next digit of the answer. 
Result so far: 177192.064039
If we subtract 3654 from 3820, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 15:
The number 406 fits into 1660 4 times, leaving a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 177192.0640394
If we take 1624 away from 1660, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 16:
406 goes into 360 0 times with a remainder of 360.
The next digit of our result is 0. 
Result so far: 177192.0640394
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The quotient of the division is 177192.0640394, and the remainder is 3.6e-07.
