We divide 42668669 by 86
Our goal is to divide 42668669 by 86.

Step 1:
86 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 86

Advancing to step 2:
86 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 86

Advancing to step 3:
86 can be fit into 426 4 times, resulting in a remainder of 82.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 344 from 426 leaves us with 82.
Take the next digit (6) from the dividend and append it to 82, then repeat: 826 / 86

Step 4:
When dividing 826 by 86, we get 9 with a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we subtract 774 from 826, we get 52.
Take the next digit (8) from the dividend and append it to 52, then repeat: 528 / 86

On to step 5:
The number 86 fits into 528 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 496.0
If we take 516 away from 528, we end up with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 86

Let's proceed to step 6:
126 divided by 86 is 1 with a remainder of 40.
The next digit of our result is 1. 
Result so far: 4961.0
Subtract 86 from 126 to get 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 86

Going ahead to step 7:
406 divided by 86 is 4 with a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 49614.0
If we subtract 344 from 406, we get 62.
Include the next digit (9) from the dividend after 62, then repeat: 629 / 86

Step 8:
86 goes into 629 7 times with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 496147.0
If we subtract 602 from 629, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
270 divided by 86 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 496147.3
If we subtract 258 from 270, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
When dividing 120 by 86, we get 1 with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 496147.31
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
86 can be fit into 340 3 times, resulting in a remainder of 82.
The next digit of our result is 3. 
Result so far: 496147.313
Subtracting 258 from 340 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 12:
When dividing 820 by 86, we get 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 496147.3139
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
86 goes into 460 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 496147.31395
If we subtract 430 from 460, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
300 divided by 86 is 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 496147.313953
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 15:
The number 86 fits into 420 4 times, leaving a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 496147.3139534
Subtracting 344 from 420 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 16:
86 can be fit into 760 8 times, resulting in a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 496147.31395348
If we take 688 away from 760, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 496147.31395348 with a remainder of 7.2e-08.
