We're dividing 3515194 by 871 
We want to figure out the number of times 3515194 can be divided by 871.

On to step 1:
3 divided by 871 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 871

Step 2:
If we divide 35 by 871, we get 0 and a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 871

Going ahead to step 3:
871 can be fit into 351 0 times, resulting in a remainder of 351.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 351 and we're left with 351.
Take the next digit (5) from the dividend and append it to 351, then repeat: 3515 / 871

Let's proceed to step 4:
871 can be fit into 3515 4 times, resulting in a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3484 from 3515 to get 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 871

On to step 5:
If we divide 311 by 871, we get 0 and a remainder of 311.
Use 0 as the next digit of our solution. 
Result so far: 40.0
The remainder is 311 after subtracting 0 from 311.
Bring next digit (9) of the dividend behind the 311 and repeat the process: 3119 / 871

Let's proceed to step 6:
871 goes into 3119 3 times with a remainder of 506.
The number 3 becomes the next digit in our result. 
Result so far: 403.0
If we take 2613 away from 3119, we end up with 506.
Bring next digit (4) of the dividend behind the 506 and repeat the process: 5064 / 871

Let's proceed to step 7:
When dividing 5064 by 871, we get 5 with a remainder of 709.
Write down 5 as next digit of the result. 
Result so far: 4035.0
Subtracting 4355 from 5064 leaves us with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

On to step 8:
The number 871 fits into 7090 8 times, leaving a remainder of 122.
Write down 8 as next digit of the result. 
Result so far: 4035.8
Subtracting 6968 from 7090 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 9:
When dividing 1220 by 871, we get 1 with a remainder of 349.
The next digit of our result is 1. 
Result so far: 4035.81
The remainder is 349 after subtracting 871 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 10:
871 can be fit into 3490 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4035.814
If we take 3484 away from 3490, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
When dividing 60 by 871, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 4035.814
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
When dividing 600 by 871, we get 0 with a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 4035.814
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

After the division, we end up with 4035.814 and a remainder of 0.0006.
