8513589 ÷ 956 
We want to figure out the number of times 8513589 can be divided by 956.

On to step 1:
The number 956 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 956

Going ahead to step 2:
85 divided by 956 is 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 956

Going ahead to step 3:
956 can be fit into 851 0 times, resulting in a remainder of 851.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 851, we end up with 851.
Fetch the next digit (3) from the dividend, attach it to 851 and continue: 8513 / 956

Going ahead to step 4:
956 goes into 8513 8 times with a remainder of 865.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 7648 from 8513 and we're left with 865.
Append the next digit (5) from the dividend to 865 and continue with: 8655 / 956

Step 5:
956 can be fit into 8655 9 times, resulting in a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we subtract 8604 from 8655, we get 51.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 956

On to step 6:
956 goes into 518 0 times with a remainder of 518.
Write down 0 as next digit of the result. 
Result so far: 890.0
Subtracting 0 from 518 leaves us with 518.
Grab the next digit (9) from the dividend, add it to 518, then carry on: 5189 / 956

Advancing to step 7:
When dividing 5189 by 956, we get 5 with a remainder of 409.
Record the quotient 5 as the next digit in the result. 
Result so far: 8905.0
Subtracting 4780 from 5189 leaves us with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

On to step 8:
If we divide 4090 by 956, we get 4 and a remainder of 266.
Write down 4 as next digit of the result. 
Result so far: 8905.4
Deduct 3824 from 4090 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 9:
If we divide 2660 by 956, we get 2 and a remainder of 748.
The number 2 becomes the next digit in our result. 
Result so far: 8905.42
The remainder is 748 after subtracting 1912 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Step 10:
956 goes into 7480 7 times with a remainder of 788.
Record the quotient 7 as the next digit in the result. 
Result so far: 8905.427
The remainder is 788 after subtracting 6692 from 7480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Advancing to step 11:
956 goes into 7880 8 times with a remainder of 232.
Use 8 as the next digit of our solution. 
Result so far: 8905.4278
Deduct 7648 from 7880 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 12:
2320 divided by 956 is 2 with a remainder of 408.
Use 2 as the next digit of our solution. 
Result so far: 8905.42782
If we subtract 1912 from 2320, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 13:
If we divide 4080 by 956, we get 4 and a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 8905.427824
The remainder is 256 after subtracting 3824 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 14:
If we divide 2560 by 956, we get 2 and a remainder of 648.
Write down 2 as next digit of the result. 
Result so far: 8905.4278242
Deduct 1912 from 2560 and we're left with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Let's proceed to step 15:
956 goes into 6480 6 times with a remainder of 744.
Record the quotient 6 as the next digit in the result. 
Result so far: 8905.42782426
Deduct 5736 from 6480 and we're left with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

The final outcome is 8905.42782426, with a leftover of 7.44e-07.
