We're dividing 55396863 by 790 
We're looking to find how many times 790 goes into 55396863.

Advancing to step 1:
If we divide 5 by 790, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 790

Going ahead to step 2:
The number 790 fits into 55 0 times, leaving a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (3) from the dividend and append it to 55, then repeat: 553 / 790

On to step 3:
553 divided by 790 is 0 with a remainder of 553.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 553 to get 553.
Bring next digit (9) of the dividend behind the 553 and repeat the process: 5539 / 790

Advancing to step 4:
790 can be fit into 5539 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 5530 from 5539 and we're left with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 790

On to step 5:
If we divide 96 by 790, we get 0 and a remainder of 96.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Subtracting 0 from 96 leaves us with 96.
Fetch the next digit (8) from the dividend, attach it to 96 and continue: 968 / 790

Moving on to step 6:
968 divided by 790 is 1 with a remainder of 178.
The number 1 becomes the next digit in our result. 
Result so far: 701.0
Subtract 790 from 968 to get 178.
Include the next digit (6) from the dividend after 178, then repeat: 1786 / 790

Let's proceed to step 7:
When dividing 1786 by 790, we get 2 with a remainder of 206.
Put 2 as the next digit of the answer. 
Result so far: 7012.0
The remainder is 206 after subtracting 1580 from 1786.
Include the next digit (3) from the dividend after 206, then repeat: 2063 / 790

Let's proceed to step 8:
2063 divided by 790 is 2 with a remainder of 483.
Use 2 as the next digit of our solution. 
Result so far: 70122.0
Subtracting 1580 from 2063 leaves us with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Moving on to step 9:
790 goes into 4830 6 times with a remainder of 90.
The next digit of our result is 6. 
Result so far: 70122.6
If we take 4740 away from 4830, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
When dividing 900 by 790, we get 1 with a remainder of 110.
The next digit of our result is 1. 
Result so far: 70122.61
Subtracting 790 from 900 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 11:
1100 divided by 790 is 1 with a remainder of 310.
The next digit of our result is 1. 
Result so far: 70122.611
If we take 790 away from 1100, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

After the division, we end up with 70122.611 and a remainder of 0.031.
