We look at the division of 3587391 by 830 
Our goal is to divide 3587391 by 830.

Let's proceed to step 1:
830 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 830

Step 2:
35 divided by 830 is 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 830

Moving on to step 3:
When dividing 358 by 830, we get 0 with a remainder of 358.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 358 and we're left with 358.
Append the next digit (7) from the dividend to 358 and continue with: 3587 / 830

Advancing to step 4:
If we divide 3587 by 830, we get 4 and a remainder of 267.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3320 from 3587, we get 267.
Bring next digit (3) of the dividend behind the 267 and repeat the process: 2673 / 830

Going ahead to step 5:
830 goes into 2673 3 times with a remainder of 183.
Use 3 as the next digit of our solution. 
Result so far: 43.0
The remainder is 183 after subtracting 2490 from 2673.
Include the next digit (9) from the dividend after 183, then repeat: 1839 / 830

Going ahead to step 6:
830 goes into 1839 2 times with a remainder of 179.
Put 2 as the next digit of the answer. 
Result so far: 432.0
Subtract 1660 from 1839 to get 179.
Grab the next digit (1) from the dividend, add it to 179, then carry on: 1791 / 830

Going ahead to step 7:
The number 830 fits into 1791 2 times, leaving a remainder of 131.
Record the quotient 2 as the next digit in the result. 
Result so far: 4322.0
The remainder is 131 after subtracting 1660 from 1791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 8:
The number 830 fits into 1310 1 times, leaving a remainder of 480.
Record the quotient 1 as the next digit in the result. 
Result so far: 4322.1
If we subtract 830 from 1310, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 9:
4800 divided by 830 is 5 with a remainder of 650.
The next digit of our result is 5. 
Result so far: 4322.15
If we subtract 4150 from 4800, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 10:
6500 divided by 830 is 7 with a remainder of 690.
The next digit of our result is 7. 
Result so far: 4322.157
If we subtract 5810 from 6500, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 11:
830 can be fit into 6900 8 times, resulting in a remainder of 260.
Record the quotient 8 as the next digit in the result. 
Result so far: 4322.1578
If we take 6640 away from 6900, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 12:
The number 830 fits into 2600 3 times, leaving a remainder of 110.
Use 3 as the next digit of our solution. 
Result so far: 4322.15783
If we take 2490 away from 2600, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 13:
If we divide 1100 by 830, we get 1 and a remainder of 270.
Use 1 as the next digit of our solution. 
Result so far: 4322.157831
Subtracting 830 from 1100 leaves us 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.

Going ahead to step 14:
If we divide 2700 by 830, we get 3 and a remainder of 210.
Record the quotient 3 as the next digit in the result. 
Result so far: 4322.1578313
Deduct 2490 from 2700 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 15:
When dividing 2100 by 830, we get 2 with a remainder of 440.
Write down 2 as next digit of the result. 
Result so far: 4322.15783132
Subtract 1660 from 2100 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 4322.15783132, with a leftover of 4.4e-07.
