We're dividing 73644139 by 819 
We're looking to find how many times 819 goes into 73644139.

Moving on to step 1:
The number 819 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 819

Let's proceed to step 2:
If we divide 73 by 819, we get 0 and a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Fetch the next digit (6) from the dividend, attach it to 73 and continue: 736 / 819

Moving on to step 3:
The number 819 fits into 736 0 times, leaving a remainder of 736.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 736, we get 736.
Take the next digit (4) from the dividend and append it to 736, then repeat: 7364 / 819

Let's proceed to step 4:
When dividing 7364 by 819, we get 8 with a remainder of 812.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 6552 from 7364 and we're left with 812.
Grab the next digit (4) from the dividend, add it to 812, then carry on: 8124 / 819

On to step 5:
8124 divided by 819 is 9 with a remainder of 753.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtract 7371 from 8124 to get 753.
Grab the next digit (1) from the dividend, add it to 753, then carry on: 7531 / 819

Advancing to step 6:
7531 divided by 819 is 9 with a remainder of 160.
Put 9 as the next digit of the answer. 
Result so far: 899.0
Deduct 7371 from 7531 and we're left with 160.
Include the next digit (3) from the dividend after 160, then repeat: 1603 / 819

Let's proceed to step 7:
When dividing 1603 by 819, we get 1 with a remainder of 784.
Put 1 as the next digit of the answer. 
Result so far: 8991.0
If we take 819 away from 1603, we end up with 784.
Append the next digit (9) from the dividend to 784 and continue with: 7849 / 819

On to step 8:
If we divide 7849 by 819, we get 9 and a remainder of 478.
Record the quotient 9 as the next digit in the result. 
Result so far: 89919.0
Deduct 7371 from 7849 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 9:
When dividing 4780 by 819, we get 5 with a remainder of 685.
Write down 5 as next digit of the result. 
Result so far: 89919.5
Deduct 4095 from 4780 and we're left with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Step 10:
If we divide 6850 by 819, we get 8 and a remainder of 298.
Record the quotient 8 as the next digit in the result. 
Result so far: 89919.58
Subtract 6552 from 6850 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 11:
819 goes into 2980 3 times with a remainder of 523.
Use 3 as the next digit of our solution. 
Result so far: 89919.583
The remainder is 523 after subtracting 2457 from 2980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Moving on to step 12:
819 goes into 5230 6 times with a remainder of 316.
Write down 6 as next digit of the result. 
Result so far: 89919.5836
If we subtract 4914 from 5230, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 13:
If we divide 3160 by 819, we get 3 and a remainder of 703.
Write down 3 as next digit of the result. 
Result so far: 89919.58363
Deduct 2457 from 3160 and we're left with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Step 14:
When dividing 7030 by 819, we get 8 with a remainder of 478.
The next digit of our result is 8. 
Result so far: 89919.583638
Subtracting 6552 from 7030 leaves us with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Let's proceed to step 15:
When dividing 4780 by 819, we get 5 with a remainder of 685.
The next digit of our result is 5. 
Result so far: 89919.5836385
Deduct 4095 from 4780 and we're left with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Step 16:
819 goes into 6850 8 times with a remainder of 298.
Record the quotient 8 as the next digit in the result. 
Result so far: 89919.58363858
If we take 6552 away from 6850, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

The final outcome is 89919.58363858, with a leftover of 2.98e-07.
