4027857 ÷ 574 
We want to figure out the number of times 4027857 can be divided by 574.

On to step 1:
If we divide 4 by 574, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 574

On to step 2:
The number 574 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 574

On to step 3:
If we divide 402 by 574, we get 0 and a remainder of 402.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 402, we end up with 402.
Grab the next digit (7) from the dividend, add it to 402, then carry on: 4027 / 574

Let's proceed to step 4:
574 goes into 4027 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 4018 away from 4027, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 574

Moving on to step 5:
The number 574 fits into 98 0 times, leaving a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 70.0
Deduct 0 from 98 and we're left with 98.
Fetch the next digit (5) from the dividend, attach it to 98 and continue: 985 / 574

Step 6:
If we divide 985 by 574, we get 1 and a remainder of 411.
The number 1 becomes the next digit in our result. 
Result so far: 701.0
If we take 574 away from 985, we end up with 411.
Append the next digit (7) from the dividend to 411 and continue with: 4117 / 574

Advancing to step 7:
When dividing 4117 by 574, we get 7 with a remainder of 99.
The next digit of our result is 7. 
Result so far: 7017.0
Subtracting 4018 from 4117 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 8:
990 divided by 574 is 1 with a remainder of 416.
The number 1 becomes the next digit in our result. 
Result so far: 7017.1
Subtract 574 from 990 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 9:
When dividing 4160 by 574, we get 7 with a remainder of 142.
Put 7 as the next digit of the answer. 
Result so far: 7017.17
If we take 4018 away from 4160, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 10:
574 goes into 1420 2 times with a remainder of 272.
Put 2 as the next digit of the answer. 
Result so far: 7017.172
The remainder is 272 after subtracting 1148 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 11:
The number 574 fits into 2720 4 times, leaving a remainder of 424.
The next digit of our result is 4. 
Result so far: 7017.1724
Subtracting 2296 from 2720 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 12:
If we divide 4240 by 574, we get 7 and a remainder of 222.
Use 7 as the next digit of our solution. 
Result so far: 7017.17247
Subtract 4018 from 4240 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 13:
574 goes into 2220 3 times with a remainder of 498.
Record the quotient 3 as the next digit in the result. 
Result so far: 7017.172473
The remainder is 498 after subtracting 1722 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Going ahead to step 14:
574 can be fit into 4980 8 times, resulting in a remainder of 388.
Put 8 as the next digit of the answer. 
Result so far: 7017.1724738
The remainder is 388 after subtracting 4592 from 4980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 15:
574 can be fit into 3880 6 times, resulting in a remainder of 436.
Write down 6 as next digit of the result. 
Result so far: 7017.17247386
Subtract 3444 from 3880 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

The final outcome is 7017.17247386, with a leftover of 4.36e-07.
