40641202 divided by 641 
We want to figure out the number of times 40641202 can be divided by 641.

Advancing to step 1:
When dividing 4 by 641, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 641

Let's proceed to step 2:
641 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 641

Advancing to step 3:
406 divided by 641 is 0 with a remainder of 406.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 406, we end up with 406.
Take the next digit (4) from the dividend and append it to 406, then repeat: 4064 / 641

Step 4:
The number 641 fits into 4064 6 times, leaving a remainder of 218.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 3846 from 4064 leaves us with 218.
Grab the next digit (1) from the dividend, add it to 218, then carry on: 2181 / 641

Step 5:
2181 divided by 641 is 3 with a remainder of 258.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Subtract 1923 from 2181 to get 258.
Bring next digit (2) of the dividend behind the 258 and repeat the process: 2582 / 641

Going ahead to step 6:
641 can be fit into 2582 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 634.0
The remainder is 18 after subtracting 2564 from 2582.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 641

Going ahead to step 7:
180 divided by 641 is 0 with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 6340.0
Subtract 0 from 180 to get 180.
Grab the next digit (2) from the dividend, add it to 180, then carry on: 1802 / 641

Advancing to step 8:
641 can be fit into 1802 2 times, resulting in a remainder of 520.
Use 2 as the next digit of our solution. 
Result so far: 63402.0
If we subtract 1282 from 1802, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 9:
641 goes into 5200 8 times with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 63402.8
Subtract 5128 from 5200 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
641 can be fit into 720 1 times, resulting in a remainder of 79.
The next digit of our result is 1. 
Result so far: 63402.81
If we take 641 away from 720, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 11:
The number 641 fits into 790 1 times, leaving a remainder of 149.
Put 1 as the next digit of the answer. 
Result so far: 63402.811
Deduct 641 from 790 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

The final outcome is 63402.811, with a leftover of 0.0149.
