42912877 divided by 85 
We want to divide 42912877 by 85.

Step 1:
85 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.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 85

Let's proceed to step 2:
42 divided by 85 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 85

Going ahead to step 3:
If we divide 429 by 85, we get 5 and a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 425 away from 429, we end up with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 85

Moving on to step 4:
41 divided by 85 is 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Deduct 0 from 41 and we're left with 41.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 85

Let's proceed to step 5:
85 can be fit into 412 4 times, resulting in a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 504.0
If we take 340 away from 412, we end up with 72.
Take the next digit (8) from the dividend and append it to 72, then repeat: 728 / 85

On to step 6:
When dividing 728 by 85, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 5048.0
If we subtract 680 from 728, we get 48.
Fetch the next digit (7) from the dividend, attach it to 48 and continue: 487 / 85

Going ahead to step 7:
85 can be fit into 487 5 times, resulting in a remainder of 62.
Use 5 as the next digit of our solution. 
Result so far: 50485.0
If we take 425 away from 487, we end up with 62.
Bring next digit (7) of the dividend behind the 62 and repeat the process: 627 / 85

On to step 8:
When dividing 627 by 85, we get 7 with a remainder of 32.
The next digit of our result is 7. 
Result so far: 504857.0
If we subtract 595 from 627, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
85 goes into 320 3 times with a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 504857.3
Subtract 255 from 320 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 10:
85 goes into 650 7 times with a remainder of 55.
The next digit of our result is 7. 
Result so far: 504857.37
Subtract 595 from 650 to 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.

Let's proceed to step 11:
When dividing 550 by 85, we get 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 504857.376
If we subtract 510 from 550, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
If we divide 400 by 85, we get 4 and a remainder of 60.
The next digit of our result is 4. 
Result so far: 504857.3764
If we subtract 340 from 400, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
If we divide 600 by 85, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 504857.37647
Deduct 595 from 600 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
If we divide 50 by 85, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 504857.37647
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 15:
85 goes into 500 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 504857.3764705
Subtract 425 from 500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 16:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 504857.37647058
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 504857.37647058 with a remaining 7e-08.
