42083839 divided by 790 
We want to figure out the number of times 42083839 can be divided by 790.

On to step 1:
4 divided by 790 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 790

Step 2:
The number 790 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 790

Let's proceed to step 3:
790 goes into 420 0 times with a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 420 and we're left with 420.
Take the next digit (8) from the dividend and append it to 420, then repeat: 4208 / 790

Advancing to step 4:
790 can be fit into 4208 5 times, resulting in a remainder of 258.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 3950 from 4208 and we're left with 258.
Include the next digit (3) from the dividend after 258, then repeat: 2583 / 790

On to step 5:
790 can be fit into 2583 3 times, resulting in a remainder of 213.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we take 2370 away from 2583, we end up with 213.
Fetch the next digit (8) from the dividend, attach it to 213 and continue: 2138 / 790

Let's proceed to step 6:
790 goes into 2138 2 times with a remainder of 558.
The number 2 becomes the next digit in our result. 
Result so far: 532.0
If we subtract 1580 from 2138, we get 558.
Take the next digit (3) from the dividend and append it to 558, then repeat: 5583 / 790

Let's proceed to step 7:
When dividing 5583 by 790, we get 7 with a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 5327.0
If we take 5530 away from 5583, we end up with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 790

On to step 8:
The number 790 fits into 539 0 times, leaving a remainder of 539.
Write down 0 as next digit of the result. 
Result so far: 53270.0
If we subtract 0 from 539, we get 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Step 9:
790 can be fit into 5390 6 times, resulting in a remainder of 650.
Use 6 as the next digit of our solution. 
Result so far: 53270.6
The remainder is 650 after subtracting 4740 from 5390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 10:
790 can be fit into 6500 8 times, resulting in a remainder of 180.
Put 8 as the next digit of the answer. 
Result so far: 53270.68
If we take 6320 away from 6500, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
790 can be fit into 1800 2 times, resulting in a remainder of 220.
Use 2 as the next digit of our solution. 
Result so far: 53270.682
If we subtract 1580 from 1800, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 12:
The number 790 fits into 2200 2 times, leaving a remainder of 620.
Use 2 as the next digit of our solution. 
Result so far: 53270.6822
The remainder is 620 after subtracting 1580 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

The quotient of the division is 53270.6822, and the remainder is 0.0062.
