We divide 1215410 by 585
We're looking to find how many times 585 goes into 1215410.

Step 1:
585 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 585

On to step 2:
The number 585 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 585

Advancing to step 3:
585 goes into 121 0 times with a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 121 and we're left with 121.
Append the next digit (5) from the dividend to 121 and continue with: 1215 / 585

Let's proceed to step 4:
585 goes into 1215 2 times with a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1170 away from 1215, we end up with 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 585

On to step 5:
585 goes into 454 0 times with a remainder of 454.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 454 and we're left with 454.
Fetch the next digit (1) from the dividend, attach it to 454 and continue: 4541 / 585

Advancing to step 6:
4541 divided by 585 is 7 with a remainder of 446.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
If we take 4095 away from 4541, we end up with 446.
Bring next digit (0) of the dividend behind the 446 and repeat the process: 4460 / 585

On to step 7:
4460 divided by 585 is 7 with a remainder of 365.
The next digit of our result is 7. 
Result so far: 2077.0
If we subtract 4095 from 4460, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 8:
If we divide 3650 by 585, we get 6 and a remainder of 140.
The next digit of our result is 6. 
Result so far: 2077.6
Subtracting 3510 from 3650 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 9:
585 can be fit into 1400 2 times, resulting in a remainder of 230.
The number 2 becomes the next digit in our result. 
Result so far: 2077.62
If we subtract 1170 from 1400, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 10:
If we divide 2300 by 585, we get 3 and a remainder of 545.
Put 3 as the next digit of the answer. 
Result so far: 2077.623
Deduct 1755 from 2300 and we're left with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Advancing to step 11:
When dividing 5450 by 585, we get 9 with a remainder of 185.
The number 9 becomes the next digit in our result. 
Result so far: 2077.6239
Subtracting 5265 from 5450 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 12:
585 goes into 1850 3 times with a remainder of 95.
Use 3 as the next digit of our solution. 
Result so far: 2077.62393
The remainder is 95 after subtracting 1755 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 13:
585 can be fit into 950 1 times, resulting in a remainder of 365.
Use 1 as the next digit of our solution. 
Result so far: 2077.623931
The remainder is 365 after subtracting 585 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 14:
When dividing 3650 by 585, we get 6 with a remainder of 140.
The number 6 becomes the next digit in our result. 
Result so far: 2077.6239316
Subtract 3510 from 3650 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 15:
585 goes into 1400 2 times with a remainder of 230.
The number 2 becomes the next digit in our result. 
Result so far: 2077.62393162
If we subtract 1170 from 1400, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final result is 2077.62393162 with a remainder of 2.3e-07.
