Let's divide 77819030 by 73
We want to figure out the number of times 77819030 can be divided by 73.

On to step 1:
7 divided by 73 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 73

Let's proceed to step 2:
When dividing 77 by 73, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 73 from 77 to get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 73

On to step 3:
73 goes into 48 0 times with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 48 leaves us with 48.
Take the next digit (1) from the dividend and append it to 48, then repeat: 481 / 73

Going ahead to step 4:
If we divide 481 by 73, we get 6 and a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Subtracting 438 from 481 leaves us with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 73

Going ahead to step 5:
The number 73 fits into 439 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 1066.0
Subtract 438 from 439 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 73

On to step 6:
10 divided by 73 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10660.0
If we take 0 away from 10, we end up with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 73

Moving on to step 7:
103 divided by 73 is 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 106601.0
If we subtract 73 from 103, we get 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 73

Going ahead to step 8:
The number 73 fits into 300 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 1066014.0
Deduct 292 from 300 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
73 can be fit into 80 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 1066014.1
Deduct 73 from 80 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
70 divided by 73 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 1066014.1
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
700 divided by 73 is 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 1066014.109
Subtracting 657 from 700 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 12:
When dividing 430 by 73, we get 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 1066014.1095
The remainder is 65 after subtracting 365 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 13:
73 can be fit into 650 8 times, resulting in a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 1066014.10958
If we subtract 584 from 650, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 14:
73 goes into 660 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 1066014.109589
If we subtract 657 from 660, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 15:
The number 73 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1066014.109589
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 16:
If we divide 300 by 73, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 1066014.10958904
Deduct 292 from 300 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 1066014.10958904 with a remaining 8e-09.
