We look at the division of 68578450 by 689 
Our goal is to divide 68578450 by 689.

Going ahead to step 1:
When dividing 6 by 689, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 689

Let's proceed to step 2:
If we divide 68 by 689, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Include the next digit (5) from the dividend after 68, then repeat: 685 / 689

Moving on to step 3:
685 divided by 689 is 0 with a remainder of 685.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 685 leaves us with 685.
Include the next digit (7) from the dividend after 685, then repeat: 6857 / 689

Step 4:
689 goes into 6857 9 times with a remainder of 656.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 6201 from 6857 leaves us with 656.
Bring next digit (8) of the dividend behind the 656 and repeat the process: 6568 / 689

Going ahead to step 5:
If we divide 6568 by 689, we get 9 and a remainder of 367.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we subtract 6201 from 6568, we get 367.
Fetch the next digit (4) from the dividend, attach it to 367 and continue: 3674 / 689

On to step 6:
If we divide 3674 by 689, we get 5 and a remainder of 229.
Write down 5 as next digit of the result. 
Result so far: 995.0
The remainder is 229 after subtracting 3445 from 3674.
Bring next digit (5) of the dividend behind the 229 and repeat the process: 2295 / 689

Moving on to step 7:
If we divide 2295 by 689, we get 3 and a remainder of 228.
Write down 3 as next digit of the result. 
Result so far: 9953.0
Deduct 2067 from 2295 and we're left with 228.
Append the next digit (0) from the dividend to 228 and continue with: 2280 / 689

Moving on to step 8:
The number 689 fits into 2280 3 times, leaving a remainder of 213.
The number 3 becomes the next digit in our result. 
Result so far: 99533.0
Deduct 2067 from 2280 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Going ahead to step 9:
689 can be fit into 2130 3 times, resulting in a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 99533.3
Subtract 2067 from 2130 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 10:
689 goes into 630 0 times with a remainder of 630.
Record the quotient 0 as the next digit in the result. 
Result so far: 99533.3
If we take 0 away from 630, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 11:
The number 689 fits into 6300 9 times, leaving a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 99533.309
The remainder is 99 after subtracting 6201 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 12:
If we divide 990 by 689, we get 1 and a remainder of 301.
Record the quotient 1 as the next digit in the result. 
Result so far: 99533.3091
Deduct 689 from 990 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 13:
689 can be fit into 3010 4 times, resulting in a remainder of 254.
Record the quotient 4 as the next digit in the result. 
Result so far: 99533.30914
Subtracting 2756 from 3010 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 14:
When dividing 2540 by 689, we get 3 with a remainder of 473.
Use 3 as the next digit of our solution. 
Result so far: 99533.309143
Deduct 2067 from 2540 and we're left with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Advancing to step 15:
689 goes into 4730 6 times with a remainder of 596.
The number 6 becomes the next digit in our result. 
Result so far: 99533.3091436
Subtracting 4134 from 4730 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 16:
When dividing 5960 by 689, we get 8 with a remainder of 448.
Put 8 as the next digit of the answer. 
Result so far: 99533.30914368
Subtracting 5512 from 5960 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final outcome is 99533.30914368, with a leftover of 4.48e-07.
