Let's divide 40988465 by 641
We're looking to find how many times 641 goes into 40988465.

On to step 1:
641 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
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:
If we divide 40 by 641, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 641

Step 3:
409 divided by 641 is 0 with a remainder of 409.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 409, we end up with 409.
Grab the next digit (8) from the dividend, add it to 409, then carry on: 4098 / 641

Advancing to step 4:
641 goes into 4098 6 times with a remainder of 252.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 3846 from 4098 leaves us with 252.
Include the next digit (8) from the dividend after 252, then repeat: 2528 / 641

Going ahead to step 5:
641 goes into 2528 3 times with a remainder of 605.
Write down 3 as next digit of the result. 
Result so far: 63.0
The remainder is 605 after subtracting 1923 from 2528.
Fetch the next digit (4) from the dividend, attach it to 605 and continue: 6054 / 641

Let's proceed to step 6:
If we divide 6054 by 641, we get 9 and a remainder of 285.
Use 9 as the next digit of our solution. 
Result so far: 639.0
The remainder is 285 after subtracting 5769 from 6054.
Include the next digit (6) from the dividend after 285, then repeat: 2856 / 641

Going ahead to step 7:
2856 divided by 641 is 4 with a remainder of 292.
Write down 4 as next digit of the result. 
Result so far: 6394.0
If we take 2564 away from 2856, we end up with 292.
Fetch the next digit (5) from the dividend, attach it to 292 and continue: 2925 / 641

Moving on to step 8:
The number 641 fits into 2925 4 times, leaving a remainder of 361.
Put 4 as the next digit of the answer. 
Result so far: 63944.0
If we take 2564 away from 2925, we end up with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

On to step 9:
3610 divided by 641 is 5 with a remainder of 405.
Put 5 as the next digit of the answer. 
Result so far: 63944.5
Deduct 3205 from 3610 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 10:
When dividing 4050 by 641, we get 6 with a remainder of 204.
Put 6 as the next digit of the answer. 
Result so far: 63944.56
If we take 3846 away from 4050, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 11:
The number 641 fits into 2040 3 times, leaving a remainder of 117.
The next digit of our result is 3. 
Result so far: 63944.563
Deduct 1923 from 2040 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 12:
The number 641 fits into 1170 1 times, leaving a remainder of 529.
Put 1 as the next digit of the answer. 
Result so far: 63944.5631
The remainder is 529 after subtracting 641 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Advancing to step 13:
If we divide 5290 by 641, we get 8 and a remainder of 162.
Write down 8 as next digit of the result. 
Result so far: 63944.56318
If we subtract 5128 from 5290, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 14:
If we divide 1620 by 641, we get 2 and a remainder of 338.
Record the quotient 2 as the next digit in the result. 
Result so far: 63944.563182
If we take 1282 away from 1620, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 15:
When dividing 3380 by 641, we get 5 with a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 63944.5631825
Subtract 3205 from 3380 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 16:
The number 641 fits into 1750 2 times, leaving a remainder of 468.
The next digit of our result is 2. 
Result so far: 63944.56318252
Deduct 1282 from 1750 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

In conclusion, the division gives 63944.56318252 with a balance of 4.68e-07.
