640072 ÷ 41 
We're looking to find how many times 41 goes into 640072.

Going ahead to step 1:
If we divide 6 by 41, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 41

Let's proceed to step 2:
The number 41 fits into 64 1 times, leaving a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 41 from 64, we get 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 41

Going ahead to step 3:
When dividing 230 by 41, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 205 from 230, we get 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 41

Advancing to step 4:
41 can be fit into 250 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
If we subtract 246 from 250, we get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 41

Step 5:
41 goes into 47 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1561.0
If we subtract 41 from 47, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 41

Advancing to step 6:
If we divide 62 by 41, we get 1 and a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 15611.0
If we subtract 41 from 62, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
The number 41 fits into 210 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 15611.5
Subtract 205 from 210 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
41 goes into 50 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 15611.51
Deduct 41 from 50 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
When dividing 90 by 41, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 15611.512
Deduct 82 from 90 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
41 can be fit into 80 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 15611.5121
Deduct 41 from 80 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
The number 41 fits into 390 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 15611.51219
Subtracting 369 from 390 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
41 can be fit into 210 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 15611.512195
The remainder is 5 after subtracting 205 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
If we divide 50 by 41, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 15611.5121951
The remainder is 9 after subtracting 41 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
90 divided by 41 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 15611.51219512
The remainder is 8 after subtracting 82 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 15611.51219512 and a remainder of 8e-09.
