We're dividing 1643381 by 790 
Our goal is to divide 1643381 by 790.

Advancing to step 1:
When dividing 1 by 790, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 790

Step 2:
If we divide 16 by 790, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 790

Going ahead to step 3:
164 divided by 790 is 0 with a remainder of 164.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 164, we end up with 164.
Take the next digit (3) from the dividend and append it to 164, then repeat: 1643 / 790

Going ahead to step 4:
The number 790 fits into 1643 2 times, leaving a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1580 from 1643 to get 63.
Grab the next digit (3) from the dividend, add it to 63, then carry on: 633 / 790

Step 5:
790 goes into 633 0 times with a remainder of 633.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 633, we get 633.
Fetch the next digit (8) from the dividend, attach it to 633 and continue: 6338 / 790

On to step 6:
790 can be fit into 6338 8 times, resulting in a remainder of 18.
The next digit of our result is 8. 
Result so far: 208.0
If we subtract 6320 from 6338, we get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 790

Let's proceed to step 7:
When dividing 181 by 790, we get 0 with a remainder of 181.
Put 0 as the next digit of the answer. 
Result so far: 2080.0
Subtract 0 from 181 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Step 8:
790 can be fit into 1810 2 times, resulting in a remainder of 230.
The number 2 becomes the next digit in our result. 
Result so far: 2080.2
If we subtract 1580 from 1810, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 9:
The number 790 fits into 2300 2 times, leaving a remainder of 720.
Record the quotient 2 as the next digit in the result. 
Result so far: 2080.22
The remainder is 720 after subtracting 1580 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

In conclusion, the division gives 2080.22 with a balance of 0.72.
