42645982 divided by 649 
We want to divide 42645982 by 649.

Going ahead to step 1:
When dividing 4 by 649, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 649

Going ahead to step 2:
649 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 649

Advancing to step 3:
426 divided by 649 is 0 with a remainder of 426.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 426 after subtracting 0 from 426.
Include the next digit (4) from the dividend after 426, then repeat: 4264 / 649

Moving on to step 4:
The number 649 fits into 4264 6 times, leaving a remainder of 370.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 3894 from 4264, we get 370.
Fetch the next digit (5) from the dividend, attach it to 370 and continue: 3705 / 649

Step 5:
If we divide 3705 by 649, we get 5 and a remainder of 460.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Deduct 3245 from 3705 and we're left with 460.
Fetch the next digit (9) from the dividend, attach it to 460 and continue: 4609 / 649

Moving on to step 6:
If we divide 4609 by 649, we get 7 and a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 657.0
If we take 4543 away from 4609, we end up with 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 649

Step 7:
649 goes into 668 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 6571.0
If we subtract 649 from 668, we get 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 649

Advancing to step 8:
When dividing 192 by 649, we get 0 with a remainder of 192.
Use 0 as the next digit of our solution. 
Result so far: 65710.0
Subtract 0 from 192 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 9:
1920 divided by 649 is 2 with a remainder of 622.
The number 2 becomes the next digit in our result. 
Result so far: 65710.2
If we take 1298 away from 1920, we end up with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Advancing to step 10:
649 can be fit into 6220 9 times, resulting in a remainder of 379.
The number 9 becomes the next digit in our result. 
Result so far: 65710.29
Deduct 5841 from 6220 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Step 11:
649 goes into 3790 5 times with a remainder of 545.
The number 5 becomes the next digit in our result. 
Result so far: 65710.295
Subtract 3245 from 3790 to get 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Let's proceed to step 12:
The number 649 fits into 5450 8 times, leaving a remainder of 258.
Write down 8 as next digit of the result. 
Result so far: 65710.2958
If we take 5192 away from 5450, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 13:
2580 divided by 649 is 3 with a remainder of 633.
The number 3 becomes the next digit in our result. 
Result so far: 65710.29583
Deduct 1947 from 2580 and we're left with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Advancing to step 14:
The number 649 fits into 6330 9 times, leaving a remainder of 489.
Record the quotient 9 as the next digit in the result. 
Result so far: 65710.295839
The remainder is 489 after subtracting 5841 from 6330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Step 15:
The number 649 fits into 4890 7 times, leaving a remainder of 347.
The number 7 becomes the next digit in our result. 
Result so far: 65710.2958397
If we subtract 4543 from 4890, we get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 16:
If we divide 3470 by 649, we get 5 and a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 65710.29583975
If we take 3245 away from 3470, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The final result is 65710.29583975 with a remainder of 2.25e-07.
