We're dividing 54090622 by 790 
We want to divide 54090622 by 790.

Advancing to step 1:
The number 790 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 790

Step 2:
The number 790 fits into 54 0 times, leaving a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Bring next digit (0) of the dividend behind the 54 and repeat the process: 540 / 790

Step 3:
When dividing 540 by 790, we get 0 with a remainder of 540.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 540 leaves us with 540.
Append the next digit (9) from the dividend to 540 and continue with: 5409 / 790

Going ahead to step 4:
5409 divided by 790 is 6 with a remainder of 669.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 4740 from 5409 leaves us with 669.
Append the next digit (0) from the dividend to 669 and continue with: 6690 / 790

Moving on to step 5:
When dividing 6690 by 790, we get 8 with a remainder of 370.
The next digit of our result is 8. 
Result so far: 68.0
The remainder is 370 after subtracting 6320 from 6690.
Fetch the next digit (6) from the dividend, attach it to 370 and continue: 3706 / 790

Let's proceed to step 6:
When dividing 3706 by 790, we get 4 with a remainder of 546.
Use 4 as the next digit of our solution. 
Result so far: 684.0
If we subtract 3160 from 3706, we get 546.
Append the next digit (2) from the dividend to 546 and continue with: 5462 / 790

Moving on to step 7:
790 can be fit into 5462 6 times, resulting in a remainder of 722.
The next digit of our result is 6. 
Result so far: 6846.0
If we subtract 4740 from 5462, we get 722.
Bring next digit (2) of the dividend behind the 722 and repeat the process: 7222 / 790

Advancing to step 8:
When dividing 7222 by 790, we get 9 with a remainder of 112.
Write down 9 as next digit of the result. 
Result so far: 68469.0
Subtract 7110 from 7222 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 9:
790 goes into 1120 1 times with a remainder of 330.
The next digit of our result is 1. 
Result so far: 68469.1
Subtract 790 from 1120 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 10:
790 can be fit into 3300 4 times, resulting in a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 68469.14
Subtract 3160 from 3300 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
1400 divided by 790 is 1 with a remainder of 610.
Put 1 as the next digit of the answer. 
Result so far: 68469.141
Subtracting 790 from 1400 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 12:
790 can be fit into 6100 7 times, resulting in a remainder of 570.
Put 7 as the next digit of the answer. 
Result so far: 68469.1417
Subtracting 5530 from 6100 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 13:
When dividing 5700 by 790, we get 7 with a remainder of 170.
The number 7 becomes the next digit in our result. 
Result so far: 68469.14177
Deduct 5530 from 5700 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final result is 68469.14177 with a remainder of 0.00017.
