15126847 ÷ 852 
We want to figure out the number of times 15126847 can be divided by 852.

Let's proceed to step 1:
If we divide 1 by 852, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 852

Going ahead to step 2:
The number 852 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 852

Moving on to step 3:
151 divided by 852 is 0 with a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 151 to get 151.
Include the next digit (2) from the dividend after 151, then repeat: 1512 / 852

Step 4:
When dividing 1512 by 852, we get 1 with a remainder of 660.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 852 from 1512 to get 660.
Grab the next digit (6) from the dividend, add it to 660, then carry on: 6606 / 852

Advancing to step 5:
852 goes into 6606 7 times with a remainder of 642.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 5964 from 6606 to get 642.
Fetch the next digit (8) from the dividend, attach it to 642 and continue: 6428 / 852

On to step 6:
6428 divided by 852 is 7 with a remainder of 464.
Write down 7 as next digit of the result. 
Result so far: 177.0
If we subtract 5964 from 6428, we get 464.
Take the next digit (4) from the dividend and append it to 464, then repeat: 4644 / 852

Going ahead to step 7:
852 goes into 4644 5 times with a remainder of 384.
Use 5 as the next digit of our solution. 
Result so far: 1775.0
Deduct 4260 from 4644 and we're left with 384.
Include the next digit (7) from the dividend after 384, then repeat: 3847 / 852

On to step 8:
If we divide 3847 by 852, we get 4 and a remainder of 439.
Put 4 as the next digit of the answer. 
Result so far: 17754.0
If we subtract 3408 from 3847, we get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Step 9:
852 can be fit into 4390 5 times, resulting in a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 17754.5
If we take 4260 away from 4390, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
If we divide 1300 by 852, we get 1 and a remainder of 448.
Write down 1 as next digit of the result. 
Result so far: 17754.51
If we subtract 852 from 1300, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 11:
When dividing 4480 by 852, we get 5 with a remainder of 220.
Record the quotient 5 as the next digit in the result. 
Result so far: 17754.515
Deduct 4260 from 4480 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 12:
When dividing 2200 by 852, we get 2 with a remainder of 496.
The number 2 becomes the next digit in our result. 
Result so far: 17754.5152
Subtracting 1704 from 2200 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 13:
When dividing 4960 by 852, we get 5 with a remainder of 700.
Put 5 as the next digit of the answer. 
Result so far: 17754.51525
The remainder is 700 after subtracting 4260 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 14:
852 can be fit into 7000 8 times, resulting in a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 17754.515258
The remainder is 184 after subtracting 6816 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 15:
When dividing 1840 by 852, we get 2 with a remainder of 136.
The number 2 becomes the next digit in our result. 
Result so far: 17754.5152582
The remainder is 136 after subtracting 1704 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 16:
852 goes into 1360 1 times with a remainder of 508.
The next digit of our result is 1. 
Result so far: 17754.51525821
Deduct 852 from 1360 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

The final result is 17754.51525821 with a remainder of 5.08e-07.
