546 divided by 693 is 0 with a remainder of 546.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 546 and we're left with 546.
Fetch the next digit (4) from the dividend, attach it to 546 and continue: 5464 / 693

Step 4:
When dividing 5464 by 693, we get 7 with a remainder of 613.
The next digit of our result is 7. 
Result so far: 7.0
If we take 4851 away from 5464, we end up with 613.
Take the next digit (0) from the dividend and append it to 613, then repeat: 6130 / 693

On to step 5:
The number 693 fits into 6130 8 times, leaving a remainder of 586.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 586 after subtracting 5544 from 6130.
Fetch the next digit (2) from the dividend, attach it to 586 and continue: 5862 / 693

Advancing to step 6:
The number 693 fits into 5862 8 times, leaving a remainder of 318.
Use 8 as the next digit of our solution. 
Result so far: 788.0
If we subtract 5544 from 5862, we get 318.
Append the next digit (8) from the dividend to 318 and continue with: 3188 / 693

On to step 7:
693 can be fit into 3188 4 times, resulting in a remainder of 416.
The number 4 becomes the next digit in our result. 
Result so far: 7884.0
Deduct 2772 from 3188 and we're left with 416.
Append the next digit (7) from the dividend to 416 and continue with: 4167 / 693

Advancing to step 8:
If we divide 4167 by 693, we get 6 and a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 78846.0
Subtract 4158 from 4167 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
The number 693 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 78846.0
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
900 divided by 693 is 1 with a remainder of 207.
The next digit of our result is 1. 
Result so far: 78846.01
If we take 693 away from 900, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 11:
693 can be fit into 2070 2 times, resulting in a remainder of 684.
Put 2 as the next digit of the answer. 
Result so far: 78846.012
Subtract 1386 from 2070 to get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Advancing to step 12:
When dividing 6840 by 693, we get 9 with a remainder of 603.
Put 9 as the next digit of the answer. 
Result so far: 78846.0129
If we take 6237 away from 6840, we end up 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.

Step 13:
6030 divided by 693 is 8 with a remainder of 486.
Record the quotient 8 as the next digit in the result. 
Result so far: 78846.01298
If we subtract 5544 from 6030, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Let's proceed to step 14:
693 goes into 4860 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 78846.012987
Subtracting 4851 from 4860 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 15:
693 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 78846.012987
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 16:
If we divide 900 by 693, we get 1 and a remainder of 207.
Use 1 as the next digit of our solution. 
Result so far: 78846.01298701
The remainder is 207 after subtracting 693 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Our division results in 78846.01298701 with a remaining 2.07e-07.
