19690587 ÷ 210 
We want to divide 19690587 by 210.

Step 1:
If we divide 1 by 210, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 210

Advancing to step 2:
210 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 210

Step 3:
The number 210 fits into 196 0 times, leaving a remainder of 196.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 196, we end up with 196.
Take the next digit (9) from the dividend and append it to 196, then repeat: 1969 / 210

Let's proceed to step 4:
The number 210 fits into 1969 9 times, leaving a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 1890 away from 1969, we end up with 79.
Fetch the next digit (0) from the dividend, attach it to 79 and continue: 790 / 210

Let's proceed to step 5:
210 goes into 790 3 times with a remainder of 160.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
If we subtract 630 from 790, we get 160.
Include the next digit (5) from the dividend after 160, then repeat: 1605 / 210

Let's proceed to step 6:
210 can be fit into 1605 7 times, resulting in a remainder of 135.
Put 7 as the next digit of the answer. 
Result so far: 937.0
Deduct 1470 from 1605 and we're left with 135.
Fetch the next digit (8) from the dividend, attach it to 135 and continue: 1358 / 210

Let's proceed to step 7:
210 goes into 1358 6 times with a remainder of 98.
Record the quotient 6 as the next digit in the result. 
Result so far: 9376.0
If we subtract 1260 from 1358, we get 98.
Include the next digit (7) from the dividend after 98, then repeat: 987 / 210

Let's proceed to step 8:
987 divided by 210 is 4 with a remainder of 147.
The number 4 becomes the next digit in our result. 
Result so far: 93764.0
Subtract 840 from 987 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 9:
If we divide 1470 by 210, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 93764.7
Subtract 1470 from 1470 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 210 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 93764.7
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
When dividing 0 by 210, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 93764.7
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 93764.7 with a remainder of 0.0.
