23305190 ÷ 641 
We're looking to find how many times 641 goes into 23305190.

On to step 1:
2 divided by 641 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 641

Let's proceed to step 2:
641 goes into 23 0 times with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 641

Going ahead to step 3:
641 goes into 233 0 times with a remainder of 233.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 233, we end up with 233.
Take the next digit (0) from the dividend and append it to 233, then repeat: 2330 / 641

Step 4:
If we divide 2330 by 641, we get 3 and a remainder of 407.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 407 after subtracting 1923 from 2330.
Grab the next digit (5) from the dividend, add it to 407, then carry on: 4075 / 641

Advancing to step 5:
641 goes into 4075 6 times with a remainder of 229.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 3846 away from 4075, we end up with 229.
Bring next digit (1) of the dividend behind the 229 and repeat the process: 2291 / 641

Step 6:
2291 divided by 641 is 3 with a remainder of 368.
Use 3 as the next digit of our solution. 
Result so far: 363.0
Subtract 1923 from 2291 to get 368.
Bring next digit (9) of the dividend behind the 368 and repeat the process: 3689 / 641

Going ahead to step 7:
3689 divided by 641 is 5 with a remainder of 484.
The number 5 becomes the next digit in our result. 
Result so far: 3635.0
The remainder is 484 after subtracting 3205 from 3689.
Append the next digit (0) from the dividend to 484 and continue with: 4840 / 641

On to step 8:
If we divide 4840 by 641, we get 7 and a remainder of 353.
The next digit of our result is 7. 
Result so far: 36357.0
If we subtract 4487 from 4840, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Let's proceed to step 9:
If we divide 3530 by 641, we get 5 and a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 36357.5
The remainder is 325 after subtracting 3205 from 3530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 10:
If we divide 3250 by 641, we get 5 and a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 36357.55
Deduct 3205 from 3250 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 36357.55 with a remainder of 0.045.
