We divide 51290878 by 649
Our goal is to divide 51290878 by 649.

Advancing to step 1:
If we divide 5 by 649, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 649

Moving on to step 2:
The number 649 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 649

Advancing to step 3:
When dividing 512 by 649, we get 0 with a remainder of 512.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 512, we get 512.
Include the next digit (9) from the dividend after 512, then repeat: 5129 / 649

Let's proceed to step 4:
5129 divided by 649 is 7 with a remainder of 586.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 4543 from 5129 to get 586.
Include the next digit (0) from the dividend after 586, then repeat: 5860 / 649

Step 5:
649 can be fit into 5860 9 times, resulting in a remainder of 19.
The next digit of our result is 9. 
Result so far: 79.0
If we take 5841 away from 5860, we end up with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 649

Let's proceed to step 6:
The number 649 fits into 198 0 times, leaving a remainder of 198.
Use 0 as the next digit of our solution. 
Result so far: 790.0
If we take 0 away from 198, we end up with 198.
Fetch the next digit (7) from the dividend, attach it to 198 and continue: 1987 / 649

Step 7:
649 goes into 1987 3 times with a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 7903.0
Deduct 1947 from 1987 and we're left with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 649

Step 8:
The number 649 fits into 408 0 times, leaving a remainder of 408.
Use 0 as the next digit of our solution. 
Result so far: 79030.0
Subtract 0 from 408 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 9:
649 goes into 4080 6 times with a remainder of 186.
Put 6 as the next digit of the answer. 
Result so far: 79030.6
Subtracting 3894 from 4080 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 10:
When dividing 1860 by 649, we get 2 with a remainder of 562.
The number 2 becomes the next digit in our result. 
Result so far: 79030.62
If we subtract 1298 from 1860, we get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Let's proceed to step 11:
If we divide 5620 by 649, we get 8 and a remainder of 428.
The number 8 becomes the next digit in our result. 
Result so far: 79030.628
The remainder is 428 after subtracting 5192 from 5620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 12:
649 goes into 4280 6 times with a remainder of 386.
Use 6 as the next digit of our solution. 
Result so far: 79030.6286
If we subtract 3894 from 4280, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 13:
The number 649 fits into 3860 5 times, leaving a remainder of 615.
Use 5 as the next digit of our solution. 
Result so far: 79030.62865
If we subtract 3245 from 3860, we get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Advancing to step 14:
649 can be fit into 6150 9 times, resulting in a remainder of 309.
The number 9 becomes the next digit in our result. 
Result so far: 79030.628659
If we subtract 5841 from 6150, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 15:
The number 649 fits into 3090 4 times, leaving a remainder of 494.
The number 4 becomes the next digit in our result. 
Result so far: 79030.6286594
Subtract 2596 from 3090 to get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Let's proceed to step 16:
If we divide 4940 by 649, we get 7 and a remainder of 397.
Write down 7 as next digit of the result. 
Result so far: 79030.62865947
The remainder is 397 after subtracting 4543 from 4940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

After the division, we end up with 79030.62865947 and a remainder of 3.97e-07.
