42126807 ÷ 83 
Let's see how many times 83 fits into 42126807.

Step 1:
83 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 83

Advancing to step 2:
83 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 83

Going ahead to step 3:
83 goes into 421 5 times with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 415 from 421 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 83

Moving on to step 4:
If we divide 62 by 83, we get 0 and a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 62 to get 62.
Bring next digit (6) of the dividend behind the 62 and repeat the process: 626 / 83

Going ahead to step 5:
83 goes into 626 7 times with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 507.0
Deduct 581 from 626 and we're left with 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 83

Let's proceed to step 6:
83 can be fit into 458 5 times, resulting in a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 5075.0
Subtracting 415 from 458 leaves us with 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 83

Step 7:
83 goes into 430 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 50755.0
Subtract 415 from 430 to get 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 83

Let's proceed to step 8:
The number 83 fits into 157 1 times, leaving a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 507551.0
If we take 83 away from 157, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 9:
740 divided by 83 is 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 507551.8
Subtract 664 from 740 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
760 divided by 83 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 507551.89
Subtracting 747 from 760 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
130 divided by 83 is 1 with a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 507551.891
Subtracting 83 from 130 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 12:
83 can be fit into 470 5 times, resulting in a remainder of 55.
The next digit of our result is 5. 
Result so far: 507551.8915
If we subtract 415 from 470, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 13:
83 can be fit into 550 6 times, resulting in a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 507551.89156
Deduct 498 from 550 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
The number 83 fits into 520 6 times, leaving a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 507551.891566
If we take 498 away from 520, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 507551.891566 with a balance of 2.2e-06.
