Let's divide 42315806 by 579
Let's see how many times 579 fits into 42315806.

Going ahead to step 1:
The number 579 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 579

Moving on to step 2:
42 divided by 579 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 579

Advancing to step 3:
When dividing 423 by 579, we get 0 with a remainder of 423.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 423, we get 423.
Append the next digit (1) from the dividend to 423 and continue with: 4231 / 579

Moving on to step 4:
The number 579 fits into 4231 7 times, leaving a remainder of 178.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 4053 from 4231, we get 178.
Include the next digit (5) from the dividend after 178, then repeat: 1785 / 579

Let's proceed to step 5:
When dividing 1785 by 579, we get 3 with a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we take 1737 away from 1785, we end up with 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 579

Let's proceed to step 6:
488 divided by 579 is 0 with a remainder of 488.
Record the quotient 0 as the next digit in the result. 
Result so far: 730.0
Deduct 0 from 488 and we're left with 488.
Fetch the next digit (0) from the dividend, attach it to 488 and continue: 4880 / 579

Let's proceed to step 7:
If we divide 4880 by 579, we get 8 and a remainder of 248.
Record the quotient 8 as the next digit in the result. 
Result so far: 7308.0
The remainder is 248 after subtracting 4632 from 4880.
Grab the next digit (6) from the dividend, add it to 248, then carry on: 2486 / 579

Step 8:
579 can be fit into 2486 4 times, resulting in a remainder of 170.
Record the quotient 4 as the next digit in the result. 
Result so far: 73084.0
Subtract 2316 from 2486 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 9:
If we divide 1700 by 579, we get 2 and a remainder of 542.
Put 2 as the next digit of the answer. 
Result so far: 73084.2
Subtract 1158 from 1700 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Let's proceed to step 10:
579 goes into 5420 9 times with a remainder of 209.
Record the quotient 9 as the next digit in the result. 
Result so far: 73084.29
If we subtract 5211 from 5420, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 11:
If we divide 2090 by 579, we get 3 and a remainder of 353.
Record the quotient 3 as the next digit in the result. 
Result so far: 73084.293
Subtract 1737 from 2090 to get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Going ahead to step 12:
579 goes into 3530 6 times with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 73084.2936
Subtracting 3474 from 3530 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
When dividing 560 by 579, we get 0 with a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 73084.2936
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 14:
579 can be fit into 5600 9 times, resulting in a remainder of 389.
Use 9 as the next digit of our solution. 
Result so far: 73084.293609
Deduct 5211 from 5600 and we're left with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Step 15:
3890 divided by 579 is 6 with a remainder of 416.
Put 6 as the next digit of the answer. 
Result so far: 73084.2936096
Subtracting 3474 from 3890 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 16:
579 can be fit into 4160 7 times, resulting in a remainder of 107.
Use 7 as the next digit of our solution. 
Result so far: 73084.29360967
If we take 4053 away from 4160, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Our division results in 73084.29360967 with a remaining 1.07e-07.
