1557071 divided by 813 
We want to figure out the number of times 1557071 can be divided by 813.

Step 1:
813 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 813

Step 2:
813 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 813

On to step 3:
813 goes into 155 0 times with a remainder of 155.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 155 to get 155.
Fetch the next digit (7) from the dividend, attach it to 155 and continue: 1557 / 813

On to step 4:
813 can be fit into 1557 1 times, resulting in a remainder of 744.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 813 from 1557 leaves us with 744.
Fetch the next digit (0) from the dividend, attach it to 744 and continue: 7440 / 813

Moving on to step 5:
813 can be fit into 7440 9 times, resulting in a remainder of 123.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 7317 from 7440 to get 123.
Bring next digit (7) of the dividend behind the 123 and repeat the process: 1237 / 813

Going ahead to step 6:
The number 813 fits into 1237 1 times, leaving a remainder of 424.
The next digit of our result is 1. 
Result so far: 191.0
The remainder is 424 after subtracting 813 from 1237.
Append the next digit (1) from the dividend to 424 and continue with: 4241 / 813

Let's proceed to step 7:
When dividing 4241 by 813, we get 5 with a remainder of 176.
Use 5 as the next digit of our solution. 
Result so far: 1915.0
If we take 4065 away from 4241, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 8:
If we divide 1760 by 813, we get 2 and a remainder of 134.
Use 2 as the next digit of our solution. 
Result so far: 1915.2
The remainder is 134 after subtracting 1626 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 9:
The number 813 fits into 1340 1 times, leaving a remainder of 527.
The next digit of our result is 1. 
Result so far: 1915.21
Deduct 813 from 1340 and we're left with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Let's proceed to step 10:
813 goes into 5270 6 times with a remainder of 392.
Write down 6 as next digit of the result. 
Result so far: 1915.216
Subtracting 4878 from 5270 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 11:
When dividing 3920 by 813, we get 4 with a remainder of 668.
The number 4 becomes the next digit in our result. 
Result so far: 1915.2164
Deduct 3252 from 3920 and we're left with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Advancing to step 12:
When dividing 6680 by 813, we get 8 with a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 1915.21648
Deduct 6504 from 6680 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 13:
813 can be fit into 1760 2 times, resulting in a remainder of 134.
Put 2 as the next digit of the answer. 
Result so far: 1915.216482
If we subtract 1626 from 1760, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 14:
When dividing 1340 by 813, we get 1 with a remainder of 527.
Use 1 as the next digit of our solution. 
Result so far: 1915.2164821
If we subtract 813 from 1340, we get 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Advancing to step 15:
813 goes into 5270 6 times with a remainder of 392.
Put 6 as the next digit of the answer. 
Result so far: 1915.21648216
The remainder is 392 after subtracting 4878 from 5270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The final result is 1915.21648216 with a remainder of 3.92e-07.
