4164921 ÷ 315 
We want to divide 4164921 by 315.

Let's proceed to step 1:
When dividing 4 by 315, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 315

Moving on to step 2:
315 can be fit into 41 0 times, resulting in a remainder of 41.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Append the next digit (6) from the dividend to 41 and continue with: 416 / 315

Going ahead to step 3:
315 can be fit into 416 1 times, resulting in a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 315 from 416 to get 101.
Grab the next digit (4) from the dividend, add it to 101, then carry on: 1014 / 315

Going ahead to step 4:
If we divide 1014 by 315, we get 3 and a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 945 from 1014, we get 69.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 315

On to step 5:
When dividing 699 by 315, we get 2 with a remainder of 69.
The next digit of our result is 2. 
Result so far: 132.0
If we subtract 630 from 699, we get 69.
Append the next digit (2) from the dividend to 69 and continue with: 692 / 315

Going ahead to step 6:
When dividing 692 by 315, we get 2 with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 1322.0
The remainder is 62 after subtracting 630 from 692.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 315

Going ahead to step 7:
The number 315 fits into 621 1 times, leaving a remainder of 306.
The next digit of our result is 1. 
Result so far: 13221.0
Deduct 315 from 621 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 8:
315 goes into 3060 9 times with a remainder of 225.
Put 9 as the next digit of the answer. 
Result so far: 13221.9
Deduct 2835 from 3060 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 9:
If we divide 2250 by 315, we get 7 and a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 13221.97
If we subtract 2205 from 2250, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
The number 315 fits into 450 1 times, leaving a remainder of 135.
Record the quotient 1 as the next digit in the result. 
Result so far: 13221.971
The remainder is 135 after subtracting 315 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 11:
1350 divided by 315 is 4 with a remainder of 90.
Put 4 as the next digit of the answer. 
Result so far: 13221.9714
Subtracting 1260 from 1350 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
315 can be fit into 900 2 times, resulting in a remainder of 270.
Write down 2 as next digit of the result. 
Result so far: 13221.97142
Deduct 630 from 900 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 13:
2700 divided by 315 is 8 with a remainder of 180.
Record the quotient 8 as the next digit in the result. 
Result so far: 13221.971428
Subtract 2520 from 2700 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 14:
When dividing 1800 by 315, we get 5 with a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 13221.9714285
Subtract 1575 from 1800 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 15:
2250 divided by 315 is 7 with a remainder of 45.
The next digit of our result is 7. 
Result so far: 13221.97142857
Subtracting 2205 from 2250 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 13221.97142857, with a leftover of 4.5e-08.
