Let's divide 15814382 by 210
Let's see how many times 210 fits into 15814382.

On to step 1:
210 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 210

Let's proceed to step 2:
The number 210 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 210

On to step 3:
The number 210 fits into 158 0 times, leaving a remainder of 158.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 158, we get 158.
Append the next digit (1) from the dividend to 158 and continue with: 1581 / 210

Step 4:
210 can be fit into 1581 7 times, resulting in a remainder of 111.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 1470 from 1581 to get 111.
Append the next digit (4) from the dividend to 111 and continue with: 1114 / 210

Going ahead to step 5:
The number 210 fits into 1114 5 times, leaving a remainder of 64.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Deduct 1050 from 1114 and we're left with 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 210

Going ahead to step 6:
The number 210 fits into 643 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 753.0
If we subtract 630 from 643, we get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 210

Going ahead to step 7:
When dividing 138 by 210, we get 0 with a remainder of 138.
Use 0 as the next digit of our solution. 
Result so far: 7530.0
If we take 0 away from 138, we end up with 138.
Append the next digit (2) from the dividend to 138 and continue with: 1382 / 210

Step 8:
210 goes into 1382 6 times with a remainder of 122.
Use 6 as the next digit of our solution. 
Result so far: 75306.0
The remainder is 122 after subtracting 1260 from 1382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 9:
1220 divided by 210 is 5 with a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 75306.5
Subtracting 1050 from 1220 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 10:
When dividing 1700 by 210, we get 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 75306.58
The remainder is 20 after subtracting 1680 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
When dividing 200 by 210, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 75306.58
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
When dividing 2000 by 210, we get 9 with a remainder of 110.
Write down 9 as next digit of the result. 
Result so far: 75306.5809
The remainder is 110 after subtracting 1890 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 13:
When dividing 1100 by 210, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 75306.58095
If we subtract 1050 from 1100, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
When dividing 500 by 210, we get 2 with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 75306.580952
The remainder is 80 after subtracting 420 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 15:
800 divided by 210 is 3 with a remainder of 170.
The number 3 becomes the next digit in our result. 
Result so far: 75306.5809523
If we take 630 away from 800, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 16:
The number 210 fits into 1700 8 times, leaving a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 75306.58095238
Deduct 1680 from 1700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 75306.58095238 with a balance of 2e-08.
