54553406 ÷ 693 
Let's see how many times 693 fits into 54553406.

Moving on to step 1:
If we divide 5 by 693, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 693

Going ahead to step 2:
The number 693 fits into 54 0 times, leaving a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Fetch the next digit (5) from the dividend, attach it to 54 and continue: 545 / 693

Advancing to step 3:
If we divide 545 by 693, we get 0 and a remainder of 545.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 545, we end up with 545.
Fetch the next digit (5) from the dividend, attach it to 545 and continue: 5455 / 693

Advancing to step 4:
If we divide 5455 by 693, we get 7 and a remainder of 604.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 4851 from 5455 to get 604.
Grab the next digit (3) from the dividend, add it to 604, then carry on: 6043 / 693

Advancing to step 5:
If we divide 6043 by 693, we get 8 and a remainder of 499.
The next digit of our result is 8. 
Result so far: 78.0
Subtract 5544 from 6043 to get 499.
Grab the next digit (4) from the dividend, add it to 499, then carry on: 4994 / 693

On to step 6:
The number 693 fits into 4994 7 times, leaving a remainder of 143.
The number 7 becomes the next digit in our result. 
Result so far: 787.0
If we subtract 4851 from 4994, we get 143.
Include the next digit (0) from the dividend after 143, then repeat: 1430 / 693

Step 7:
The number 693 fits into 1430 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 7872.0
If we subtract 1386 from 1430, we get 44.
Grab the next digit (6) from the dividend, add it to 44, then carry on: 446 / 693

Going ahead to step 8:
446 divided by 693 is 0 with a remainder of 446.
Record the quotient 0 as the next digit in the result. 
Result so far: 78720.0
Deduct 0 from 446 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 9:
693 can be fit into 4460 6 times, resulting in a remainder of 302.
Record the quotient 6 as the next digit in the result. 
Result so far: 78720.6
If we take 4158 away from 4460, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 10:
693 goes into 3020 4 times with a remainder of 248.
The next digit of our result is 4. 
Result so far: 78720.64
Subtracting 2772 from 3020 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 11:
693 goes into 2480 3 times with a remainder of 401.
The number 3 becomes the next digit in our result. 
Result so far: 78720.643
If we take 2079 away from 2480, we end up with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

On to step 12:
When dividing 4010 by 693, we get 5 with a remainder of 545.
Record the quotient 5 as the next digit in the result. 
Result so far: 78720.6435
Subtracting 3465 from 4010 leaves us with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Going ahead to step 13:
5450 divided by 693 is 7 with a remainder of 599.
The number 7 becomes the next digit in our result. 
Result so far: 78720.64357
If we take 4851 away from 5450, we end up with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Moving on to step 14:
5990 divided by 693 is 8 with a remainder of 446.
Put 8 as the next digit of the answer. 
Result so far: 78720.643578
If we take 5544 away from 5990, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 15:
If we divide 4460 by 693, we get 6 and a remainder of 302.
Use 6 as the next digit of our solution. 
Result so far: 78720.6435786
Deduct 4158 from 4460 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 16:
The number 693 fits into 3020 4 times, leaving a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 78720.64357864
The remainder is 248 after subtracting 2772 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final result is 78720.64357864 with a remainder of 2.48e-07.
