We look at the division of 73578819 by 689 
We're looking to find how many times 689 goes into 73578819.

On to step 1:
The number 689 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 689

Going ahead to step 2:
The number 689 fits into 73 0 times, leaving a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Fetch the next digit (5) from the dividend, attach it to 73 and continue: 735 / 689

Let's proceed to step 3:
If we divide 735 by 689, we get 1 and a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 689 away from 735, we end up with 46.
Take the next digit (7) from the dividend and append it to 46, then repeat: 467 / 689

Going ahead to step 4:
When dividing 467 by 689, we get 0 with a remainder of 467.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 467, we end up with 467.
Append the next digit (8) from the dividend to 467 and continue with: 4678 / 689

Advancing to step 5:
689 can be fit into 4678 6 times, resulting in a remainder of 544.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
Subtract 4134 from 4678 to get 544.
Include the next digit (8) from the dividend after 544, then repeat: 5448 / 689

On to step 6:
689 goes into 5448 7 times with a remainder of 625.
Record the quotient 7 as the next digit in the result. 
Result so far: 1067.0
If we subtract 4823 from 5448, we get 625.
Fetch the next digit (1) from the dividend, attach it to 625 and continue: 6251 / 689

Advancing to step 7:
6251 divided by 689 is 9 with a remainder of 50.
Use 9 as the next digit of our solution. 
Result so far: 10679.0
Subtract 6201 from 6251 to get 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 689

Step 8:
689 can be fit into 509 0 times, resulting in a remainder of 509.
Use 0 as the next digit of our solution. 
Result so far: 106790.0
Deduct 0 from 509 and we're left with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Moving on to step 9:
The number 689 fits into 5090 7 times, leaving a remainder of 267.
The number 7 becomes the next digit in our result. 
Result so far: 106790.7
Subtracting 4823 from 5090 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 10:
2670 divided by 689 is 3 with a remainder of 603.
Use 3 as the next digit of our solution. 
Result so far: 106790.73
Subtracting 2067 from 2670 leaves us with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Let's proceed to step 11:
6030 divided by 689 is 8 with a remainder of 518.
Use 8 as the next digit of our solution. 
Result so far: 106790.738
Deduct 5512 from 6030 and we're left with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Moving on to step 12:
689 can be fit into 5180 7 times, resulting in a remainder of 357.
Use 7 as the next digit of our solution. 
Result so far: 106790.7387
Subtracting 4823 from 5180 leaves us with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

On to step 13:
If we divide 3570 by 689, we get 5 and a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 106790.73875
Subtracting 3445 from 3570 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 14:
When dividing 1250 by 689, we get 1 with a remainder of 561.
The number 1 becomes the next digit in our result. 
Result so far: 106790.738751
If we subtract 689 from 1250, we get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

On to step 15:
689 can be fit into 5610 8 times, resulting in a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 106790.7387518
Deduct 5512 from 5610 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 16:
980 divided by 689 is 1 with a remainder of 291.
Put 1 as the next digit of the answer. 
Result so far: 106790.73875181
The remainder is 291 after subtracting 689 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

The quotient of the division is 106790.73875181, and the remainder is 2.91e-07.
