42945098 ÷ 83 
Our goal is to divide 42945098 by 83.

Advancing to step 1:
When dividing 4 by 83, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 83

Step 2:
When dividing 42 by 83, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 83

Advancing to step 3:
When dividing 429 by 83, we get 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 14 after subtracting 415 from 429.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 83

On to step 4:
The number 83 fits into 144 1 times, leaving a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we subtract 83 from 144, we get 61.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 83

On to step 5:
When dividing 615 by 83, we get 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 517.0
Subtracting 581 from 615 leaves us with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 83

Let's proceed to step 6:
83 can be fit into 340 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 5174.0
Deduct 332 from 340 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 83

Step 7:
83 can be fit into 89 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 51741.0
If we take 83 away from 89, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 83

On to step 8:
68 divided by 83 is 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 517410.0
Subtract 0 from 68 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
The number 83 fits into 680 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 517410.8
Subtracting 664 from 680 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
The number 83 fits into 160 1 times, leaving a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 517410.81
The remainder is 77 after subtracting 83 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 11:
83 can be fit into 770 9 times, resulting in a remainder of 23.
The next digit of our result is 9. 
Result so far: 517410.819
If we take 747 away from 770, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 12:
83 can be fit into 230 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 517410.8192
Subtract 166 from 230 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
When dividing 640 by 83, we get 7 with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 517410.81927
Subtracting 581 from 640 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 14:
When dividing 590 by 83, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 517410.819277
The remainder is 9 after subtracting 581 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 517410.819277, with a leftover of 9e-07.
