We divide 15625054 by 391
Our goal is to divide 15625054 by 391.

On to step 1:
1 divided by 391 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 391

Moving on to step 2:
391 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 391

Going ahead to step 3:
When dividing 156 by 391, we get 0 with a remainder of 156.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 156, we end up with 156.
Fetch the next digit (2) from the dividend, attach it to 156 and continue: 1562 / 391

Let's proceed to step 4:
When dividing 1562 by 391, we get 3 with a remainder of 389.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 1173 from 1562, we get 389.
Grab the next digit (5) from the dividend, add it to 389, then carry on: 3895 / 391

Going ahead to step 5:
The number 391 fits into 3895 9 times, leaving a remainder of 376.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 3519 from 3895 to get 376.
Fetch the next digit (0) from the dividend, attach it to 376 and continue: 3760 / 391

On to step 6:
When dividing 3760 by 391, we get 9 with a remainder of 241.
The number 9 becomes the next digit in our result. 
Result so far: 399.0
If we take 3519 away from 3760, we end up with 241.
Fetch the next digit (5) from the dividend, attach it to 241 and continue: 2415 / 391

Moving on to step 7:
391 goes into 2415 6 times with a remainder of 69.
The number 6 becomes the next digit in our result. 
Result so far: 3996.0
If we take 2346 away from 2415, we end up with 69.
Grab the next digit (4) from the dividend, add it to 69, then carry on: 694 / 391

Step 8:
If we divide 694 by 391, we get 1 and a remainder of 303.
Use 1 as the next digit of our solution. 
Result so far: 39961.0
If we subtract 391 from 694, we get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Going ahead to step 9:
3030 divided by 391 is 7 with a remainder of 293.
The next digit of our result is 7. 
Result so far: 39961.7
Subtracting 2737 from 3030 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Going ahead to step 10:
391 can be fit into 2930 7 times, resulting in a remainder of 193.
Put 7 as the next digit of the answer. 
Result so far: 39961.77
If we take 2737 away from 2930, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

After the division, we end up with 39961.77 and a remainder of 0.193.
