We divide 15359916 by 210
Our goal is to divide 15359916 by 210.

Advancing to step 1:
If we divide 1 by 210, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 210

Going ahead to step 2:
210 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 210

Advancing to step 3:
When dividing 153 by 210, we get 0 with a remainder of 153.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 153 to get 153.
Fetch the next digit (5) from the dividend, attach it to 153 and continue: 1535 / 210

On to step 4:
If we divide 1535 by 210, we get 7 and a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 1470 from 1535 and we're left with 65.
Bring next digit (9) of the dividend behind the 65 and repeat the process: 659 / 210

Moving on to step 5:
210 can be fit into 659 3 times, resulting in a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Deduct 630 from 659 and we're left with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 210

Going ahead to step 6:
When dividing 299 by 210, we get 1 with a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 731.0
If we take 210 away from 299, we end up with 89.
Include the next digit (1) from the dividend after 89, then repeat: 891 / 210

On to step 7:
If we divide 891 by 210, we get 4 and a remainder of 51.
Write down 4 as next digit of the result. 
Result so far: 7314.0
The remainder is 51 after subtracting 840 from 891.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 210

Going ahead to step 8:
210 goes into 516 2 times with a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 73142.0
Deduct 420 from 516 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 9:
210 goes into 960 4 times with a remainder of 120.
The next digit of our result is 4. 
Result so far: 73142.4
If we take 840 away from 960, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
If we divide 1200 by 210, we get 5 and a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 73142.45
Subtract 1050 from 1200 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
When dividing 1500 by 210, we get 7 with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 73142.457
If we take 1470 away from 1500, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
210 can be fit into 300 1 times, resulting in a remainder of 90.
The next digit of our result is 1. 
Result so far: 73142.4571
Subtract 210 from 300 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 13:
900 divided by 210 is 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 73142.45714
Subtracting 840 from 900 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.

On to step 14:
210 goes into 600 2 times with a remainder of 180.
Write down 2 as next digit of the result. 
Result so far: 73142.457142
If we take 420 away from 600, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 15:
210 can be fit into 1800 8 times, resulting in a remainder of 120.
The next digit of our result is 8. 
Result so far: 73142.4571428
Subtract 1680 from 1800 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 16:
When dividing 1200 by 210, we get 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 73142.45714285
If we subtract 1050 from 1200, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The quotient of the division is 73142.45714285, and the remainder is 1.5e-07.
