Let's divide 19515710 by 849
We want to figure out the number of times 19515710 can be divided by 849.

Advancing to step 1:
If we divide 1 by 849, 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.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 849

Going ahead to step 2:
The number 849 fits into 19 0 times, leaving a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 849

Advancing to step 3:
When dividing 195 by 849, we get 0 with a remainder of 195.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 195, we end up with 195.
Append the next digit (1) from the dividend to 195 and continue with: 1951 / 849

On to step 4:
When dividing 1951 by 849, we get 2 with a remainder of 253.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1698 from 1951 to get 253.
Grab the next digit (5) from the dividend, add it to 253, then carry on: 2535 / 849

Let's proceed to step 5:
If we divide 2535 by 849, we get 2 and a remainder of 837.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 1698 from 2535 to get 837.
Fetch the next digit (7) from the dividend, attach it to 837 and continue: 8377 / 849

Moving on to step 6:
When dividing 8377 by 849, we get 9 with a remainder of 736.
Put 9 as the next digit of the answer. 
Result so far: 229.0
The remainder is 736 after subtracting 7641 from 8377.
Grab the next digit (1) from the dividend, add it to 736, then carry on: 7361 / 849

Moving on to step 7:
849 can be fit into 7361 8 times, resulting in a remainder of 569.
Write down 8 as next digit of the result. 
Result so far: 2298.0
Deduct 6792 from 7361 and we're left with 569.
Take the next digit (0) from the dividend and append it to 569, then repeat: 5690 / 849

On to step 8:
If we divide 5690 by 849, we get 6 and a remainder of 596.
Use 6 as the next digit of our solution. 
Result so far: 22986.0
Deduct 5094 from 5690 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 9:
849 can be fit into 5960 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 22986.7
If we take 5943 away from 5960, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
170 divided by 849 is 0 with a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 22986.7
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 11:
When dividing 1700 by 849, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 22986.702
Deduct 1698 from 1700 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
When dividing 20 by 849, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 22986.702
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
849 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 22986.702
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 22986.702 with a balance of 0.0002.
