Let's divide 16443408 by 865
Our goal is to divide 16443408 by 865.

Advancing to step 1:
1 divided by 865 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 865

Going ahead to step 2:
16 divided by 865 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 865

On to step 3:
865 goes into 164 0 times with a remainder of 164.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 164 and we're left with 164.
Grab the next digit (4) from the dividend, add it to 164, then carry on: 1644 / 865

Going ahead to step 4:
1644 divided by 865 is 1 with a remainder of 779.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 779 after subtracting 865 from 1644.
Append the next digit (3) from the dividend to 779 and continue with: 7793 / 865

On to step 5:
The number 865 fits into 7793 9 times, leaving a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 8 after subtracting 7785 from 7793.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 865

Step 6:
84 divided by 865 is 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
If we take 0 away from 84, we end up with 84.
Include the next digit (0) from the dividend after 84, then repeat: 840 / 865

Advancing to step 7:
865 goes into 840 0 times with a remainder of 840.
Use 0 as the next digit of our solution. 
Result so far: 1900.0
If we take 0 away from 840, we end up with 840.
Grab the next digit (8) from the dividend, add it to 840, then carry on: 8408 / 865

Let's proceed to step 8:
865 goes into 8408 9 times with a remainder of 623.
Record the quotient 9 as the next digit in the result. 
Result so far: 19009.0
Deduct 7785 from 8408 and we're left with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Advancing to step 9:
When dividing 6230 by 865, we get 7 with a remainder of 175.
Use 7 as the next digit of our solution. 
Result so far: 19009.7
The remainder is 175 after subtracting 6055 from 6230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 10:
The number 865 fits into 1750 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 19009.72
Deduct 1730 from 1750 and we're left with 20.
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 11:
When dividing 200 by 865, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 19009.72
Deduct 0 from 200 and we're left 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 12:
The number 865 fits into 2000 2 times, leaving a remainder of 270.
The number 2 becomes the next digit in our result. 
Result so far: 19009.7202
The remainder is 270 after subtracting 1730 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 13:
865 goes into 2700 3 times with a remainder of 105.
Record the quotient 3 as the next digit in the result. 
Result so far: 19009.72023
Subtracting 2595 from 2700 leaves us 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.

Advancing to step 14:
1050 divided by 865 is 1 with a remainder of 185.
The number 1 becomes the next digit in our result. 
Result so far: 19009.720231
If we subtract 865 from 1050, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 15:
When dividing 1850 by 865, we get 2 with a remainder of 120.
The next digit of our result is 2. 
Result so far: 19009.7202312
If we take 1730 away from 1850, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 16:
If we divide 1200 by 865, we get 1 and a remainder of 335.
Put 1 as the next digit of the answer. 
Result so far: 19009.72023121
Subtract 865 from 1200 to 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.

The final outcome is 19009.72023121, with a leftover of 3.35e-07.
