39088042 divided by 420 
We want to divide 39088042 by 420.

Moving on to step 1:
When dividing 3 by 420, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 420

Let's proceed to step 2:
When dividing 39 by 420, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 420

Advancing to step 3:
The number 420 fits into 390 0 times, leaving a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 390 and we're left with 390.
Append the next digit (8) from the dividend to 390 and continue with: 3908 / 420

Advancing to step 4:
420 goes into 3908 9 times with a remainder of 128.
The next digit of our result is 9. 
Result so far: 9.0
If we take 3780 away from 3908, we end up with 128.
Include the next digit (8) from the dividend after 128, then repeat: 1288 / 420

Going ahead to step 5:
When dividing 1288 by 420, we get 3 with a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Subtracting 1260 from 1288 leaves us with 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 420

On to step 6:
When dividing 280 by 420, we get 0 with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 930.0
If we take 0 away from 280, we end up with 280.
Bring next digit (4) of the dividend behind the 280 and repeat the process: 2804 / 420

Step 7:
2804 divided by 420 is 6 with a remainder of 284.
Record the quotient 6 as the next digit in the result. 
Result so far: 9306.0
If we take 2520 away from 2804, we end up with 284.
Include the next digit (2) from the dividend after 284, then repeat: 2842 / 420

Advancing to step 8:
The number 420 fits into 2842 6 times, leaving a remainder of 322.
Record the quotient 6 as the next digit in the result. 
Result so far: 93066.0
Subtract 2520 from 2842 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 9:
420 can be fit into 3220 7 times, resulting in a remainder of 280.
Use 7 as the next digit of our solution. 
Result so far: 93066.7
If we take 2940 away from 3220, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 10:
If we divide 2800 by 420, we get 6 and a remainder of 280.
Record the quotient 6 as the next digit in the result. 
Result so far: 93066.76
If we subtract 2520 from 2800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
420 goes into 2800 6 times with a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 93066.766
Subtract 2520 from 2800 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 93066.766 and a remainder of 0.028.
