15962742 divided by 210 
Our goal is to divide 15962742 by 210.

Going ahead to step 1:
The number 210 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 210

Let's proceed to step 2:
15 divided by 210 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 210

On to step 3:
If we divide 159 by 210, we get 0 and a remainder of 159.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 159, we get 159.
Append the next digit (6) from the dividend to 159 and continue with: 1596 / 210

Going ahead to step 4:
The number 210 fits into 1596 7 times, leaving a remainder of 126.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 1470 from 1596 and we're left with 126.
Bring next digit (2) of the dividend behind the 126 and repeat the process: 1262 / 210

Let's proceed to step 5:
210 goes into 1262 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
If we subtract 1260 from 1262, we get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 210

On to step 6:
210 goes into 27 0 times with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 760.0
Subtract 0 from 27 to get 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 210

Step 7:
274 divided by 210 is 1 with a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 7601.0
If we take 210 away from 274, we end up with 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 210

Moving on to step 8:
210 goes into 642 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 76013.0
If we take 630 away from 642, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
If we divide 120 by 210, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 76013.0
Subtracting 0 from 120 leaves us 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.

On to step 10:
When dividing 1200 by 210, we get 5 with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 76013.05
If we take 1050 away from 1200, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 11:
1500 divided by 210 is 7 with a remainder of 30.
The next digit of our result is 7. 
Result so far: 76013.057
If we subtract 1470 from 1500, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed 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: 76013.0571
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.
The number 4 becomes the next digit in our result. 
Result so far: 76013.05714
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.

Advancing to step 14:
The number 210 fits into 600 2 times, leaving a remainder of 180.
Use 2 as the next digit of our solution. 
Result so far: 76013.057142
Deduct 420 from 600 and we're left 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.

Going ahead to step 15:
1800 divided by 210 is 8 with a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 76013.0571428
The remainder is 120 after subtracting 1680 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
The number 210 fits into 1200 5 times, leaving a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 76013.05714285
Deduct 1050 from 1200 and we're left with 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 final result is 76013.05714285 with a remainder of 1.5e-07.
