We're dividing 42092780 by 122 
We want to divide 42092780 by 122.

Step 1:
4 divided by 122 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 take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 122

On to step 2:
If we divide 42 by 122, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 122

On to step 3:
122 goes into 420 3 times with a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 366 from 420 to get 54.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 122

Moving on to step 4:
122 goes into 549 4 times with a remainder of 61.
The next digit of our result is 4. 
Result so far: 34.0
Subtracting 488 from 549 leaves us with 61.
Fetch the next digit (2) from the dividend, attach it to 61 and continue: 612 / 122

Advancing to step 5:
122 goes into 612 5 times with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 345.0
Deduct 610 from 612 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 122

Let's proceed to step 6:
122 can be fit into 27 0 times, resulting in a remainder of 27.
The next digit of our result is 0. 
Result so far: 3450.0
Subtract 0 from 27 to get 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 122

Advancing to step 7:
278 divided by 122 is 2 with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 34502.0
If we subtract 244 from 278, we get 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 122

Advancing to step 8:
340 divided by 122 is 2 with a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 345022.0
Subtract 244 from 340 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 9:
960 divided by 122 is 7 with a remainder of 106.
The number 7 becomes the next digit in our result. 
Result so far: 345022.7
The remainder is 106 after subtracting 854 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 10:
1060 divided by 122 is 8 with a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 345022.78
Subtract 976 from 1060 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 11:
122 can be fit into 840 6 times, resulting in a remainder of 108.
Use 6 as the next digit of our solution. 
Result so far: 345022.786
Subtract 732 from 840 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 12:
122 goes into 1080 8 times with a remainder of 104.
Write down 8 as next digit of the result. 
Result so far: 345022.7868
If we subtract 976 from 1080, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 13:
If we divide 1040 by 122, we get 8 and a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 345022.78688
Subtracting 976 from 1040 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 345022.78688 with a remaining 6.4e-05.
