13100946 divided by 865 
Our goal is to divide 13100946 by 865.

Step 1:
The number 865 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 865

On to step 2:
865 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 865

Going ahead to step 3:
If we divide 131 by 865, we get 0 and a remainder of 131.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 131, we get 131.
Fetch the next digit (0) from the dividend, attach it to 131 and continue: 1310 / 865

Going ahead to step 4:
The number 865 fits into 1310 1 times, leaving a remainder of 445.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 865 from 1310 and we're left with 445.
Append the next digit (0) from the dividend to 445 and continue with: 4450 / 865

On to step 5:
865 can be fit into 4450 5 times, resulting in a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 4325 from 4450, we get 125.
Grab the next digit (9) from the dividend, add it to 125, then carry on: 1259 / 865

Let's proceed to step 6:
The number 865 fits into 1259 1 times, leaving a remainder of 394.
The next digit of our result is 1. 
Result so far: 151.0
If we take 865 away from 1259, we end up with 394.
Grab the next digit (4) from the dividend, add it to 394, then carry on: 3944 / 865

Step 7:
When dividing 3944 by 865, we get 4 with a remainder of 484.
Put 4 as the next digit of the answer. 
Result so far: 1514.0
If we take 3460 away from 3944, we end up with 484.
Append the next digit (6) from the dividend to 484 and continue with: 4846 / 865

On to step 8:
865 can be fit into 4846 5 times, resulting in a remainder of 521.
Write down 5 as next digit of the result. 
Result so far: 15145.0
Deduct 4325 from 4846 and we're left with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Moving on to step 9:
When dividing 5210 by 865, we get 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 15145.6
The remainder is 20 after subtracting 5190 from 5210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
865 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 15145.6
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
2000 divided by 865 is 2 with a remainder of 270.
The next digit of our result is 2. 
Result so far: 15145.602
Deduct 1730 from 2000 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 12:
When dividing 2700 by 865, we get 3 with a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 15145.6023
If we take 2595 away from 2700, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 13:
1050 divided by 865 is 1 with a remainder of 185.
Write down 1 as next digit of the result. 
Result so far: 15145.60231
The remainder is 185 after subtracting 865 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 14:
865 can be fit into 1850 2 times, resulting in a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 15145.602312
If we subtract 1730 from 1850, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 15:
865 can be fit into 1200 1 times, resulting in a remainder of 335.
Put 1 as the next digit of the answer. 
Result so far: 15145.6023121
If we subtract 865 from 1200, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 16:
865 goes into 3350 3 times with a remainder of 755.
The next digit of our result is 3. 
Result so far: 15145.60231213
Deduct 2595 from 3350 and we're left with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

The final outcome is 15145.60231213, with a leftover of 7.55e-07.
