We look at the division of 40081630 by 620 
We're looking to find how many times 620 goes into 40081630.

Let's proceed to step 1:
4 divided by 620 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 620

Let's proceed to step 2:
620 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 620

Moving on to step 3:
620 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
The remainder is 400 after subtracting 0 from 400.
Include the next digit (8) from the dividend after 400, then repeat: 4008 / 620

On to step 4:
620 can be fit into 4008 6 times, resulting in a remainder of 288.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 3720 from 4008, we get 288.
Take the next digit (1) from the dividend and append it to 288, then repeat: 2881 / 620

Moving on to step 5:
2881 divided by 620 is 4 with a remainder of 401.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Deduct 2480 from 2881 and we're left with 401.
Append the next digit (6) from the dividend to 401 and continue with: 4016 / 620

Going ahead to step 6:
If we divide 4016 by 620, we get 6 and a remainder of 296.
Put 6 as the next digit of the answer. 
Result so far: 646.0
Subtract 3720 from 4016 to get 296.
Take the next digit (3) from the dividend and append it to 296, then repeat: 2963 / 620

On to step 7:
When dividing 2963 by 620, we get 4 with a remainder of 483.
The number 4 becomes the next digit in our result. 
Result so far: 6464.0
Subtracting 2480 from 2963 leaves us with 483.
Append the next digit (0) from the dividend to 483 and continue with: 4830 / 620

On to step 8:
620 can be fit into 4830 7 times, resulting in a remainder of 490.
Record the quotient 7 as the next digit in the result. 
Result so far: 64647.0
Subtracting 4340 from 4830 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 9:
620 goes into 4900 7 times with a remainder of 560.
The number 7 becomes the next digit in our result. 
Result so far: 64647.7
Subtract 4340 from 4900 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 10:
The number 620 fits into 5600 9 times, leaving a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 64647.79
If we take 5580 away from 5600, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
620 can be fit into 200 0 times, resulting in a remainder of 200.
The next digit of our result is 0. 
Result so far: 64647.79
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
620 can be fit into 2000 3 times, resulting in a remainder of 140.
Record the quotient 3 as the next digit in the result. 
Result so far: 64647.7903
Deduct 1860 from 2000 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 13:
1400 divided by 620 is 2 with a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 64647.79032
Deduct 1240 from 1400 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.

Step 14:
1600 divided by 620 is 2 with a remainder of 360.
Record the quotient 2 as the next digit in the result. 
Result so far: 64647.790322
Subtracting 1240 from 1600 leaves us with 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 final outcome is 64647.790322, with a leftover of 3.6e-05.
