Let's divide 40989442 by 657
We want to divide 40989442 by 657.

Step 1:
When dividing 4 by 657, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 657

Advancing to step 2:
The number 657 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 657

On to step 3:
409 divided by 657 is 0 with a remainder of 409.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 409 and we're left with 409.
Fetch the next digit (8) from the dividend, attach it to 409 and continue: 4098 / 657

Going ahead to step 4:
When dividing 4098 by 657, we get 6 with a remainder of 156.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 3942 from 4098 and we're left with 156.
Take the next digit (9) from the dividend and append it to 156, then repeat: 1569 / 657

Advancing to step 5:
1569 divided by 657 is 2 with a remainder of 255.
Write down 2 as next digit of the result. 
Result so far: 62.0
The remainder is 255 after subtracting 1314 from 1569.
Take the next digit (4) from the dividend and append it to 255, then repeat: 2554 / 657

Advancing to step 6:
2554 divided by 657 is 3 with a remainder of 583.
The next digit of our result is 3. 
Result so far: 623.0
If we subtract 1971 from 2554, we get 583.
Bring next digit (4) of the dividend behind the 583 and repeat the process: 5834 / 657

On to step 7:
If we divide 5834 by 657, we get 8 and a remainder of 578.
Write down 8 as next digit of the result. 
Result so far: 6238.0
The remainder is 578 after subtracting 5256 from 5834.
Grab the next digit (2) from the dividend, add it to 578, then carry on: 5782 / 657

Advancing to step 8:
The number 657 fits into 5782 8 times, leaving a remainder of 526.
The number 8 becomes the next digit in our result. 
Result so far: 62388.0
Subtracting 5256 from 5782 leaves us with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Let's proceed to step 9:
If we divide 5260 by 657, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 62388.8
Deduct 5256 from 5260 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
657 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 62388.8
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
400 divided by 657 is 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 62388.8
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 62388.8 and a remainder of 0.04.
