We divide 40065982 by 621
Let's see how many times 621 fits into 40065982.

On to step 1:
If we divide 4 by 621, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 621

On to step 2:
40 divided by 621 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 621

Advancing to step 3:
621 can be fit into 400 0 times, resulting in a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 400 and we're left with 400.
Fetch the next digit (6) from the dividend, attach it to 400 and continue: 4006 / 621

On to step 4:
The number 621 fits into 4006 6 times, leaving a remainder of 280.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 3726 from 4006, we get 280.
Bring next digit (5) of the dividend behind the 280 and repeat the process: 2805 / 621

Advancing to step 5:
If we divide 2805 by 621, we get 4 and a remainder of 321.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtract 2484 from 2805 to get 321.
Grab the next digit (9) from the dividend, add it to 321, then carry on: 3219 / 621

Going ahead to step 6:
When dividing 3219 by 621, we get 5 with a remainder of 114.
Record the quotient 5 as the next digit in the result. 
Result so far: 645.0
Subtracting 3105 from 3219 leaves us with 114.
Grab the next digit (8) from the dividend, add it to 114, then carry on: 1148 / 621

Advancing to step 7:
If we divide 1148 by 621, we get 1 and a remainder of 527.
The number 1 becomes the next digit in our result. 
Result so far: 6451.0
Subtract 621 from 1148 to get 527.
Append the next digit (2) from the dividend to 527 and continue with: 5272 / 621

On to step 8:
If we divide 5272 by 621, we get 8 and a remainder of 304.
Write down 8 as next digit of the result. 
Result so far: 64518.0
The remainder is 304 after subtracting 4968 from 5272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 9:
621 goes into 3040 4 times with a remainder of 556.
The number 4 becomes the next digit in our result. 
Result so far: 64518.4
Subtract 2484 from 3040 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Let's proceed to step 10:
621 can be fit into 5560 8 times, resulting in a remainder of 592.
Put 8 as the next digit of the answer. 
Result so far: 64518.48
Subtracting 4968 from 5560 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 11:
5920 divided by 621 is 9 with a remainder of 331.
The next digit of our result is 9. 
Result so far: 64518.489
Subtract 5589 from 5920 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Step 12:
621 can be fit into 3310 5 times, resulting in a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 64518.4895
The remainder is 205 after subtracting 3105 from 3310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 13:
The number 621 fits into 2050 3 times, leaving a remainder of 187.
Put 3 as the next digit of the answer. 
Result so far: 64518.48953
Subtracting 1863 from 2050 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 14:
1870 divided by 621 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 64518.489533
Deduct 1863 from 1870 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 64518.489533 and a remainder of 7e-07.
