55580139 ÷ 680 
Let's see how many times 680 fits into 55580139.

On to step 1:
680 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 680

Step 2:
When dividing 55 by 680, we get 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 680

Advancing to step 3:
The number 680 fits into 555 0 times, leaving a remainder of 555.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 555 after subtracting 0 from 555.
Take the next digit (8) from the dividend and append it to 555, then repeat: 5558 / 680

On to step 4:
680 can be fit into 5558 8 times, resulting in a remainder of 118.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 5440 from 5558 and we're left with 118.
Bring next digit (0) of the dividend behind the 118 and repeat the process: 1180 / 680

Let's proceed to step 5:
When dividing 1180 by 680, we get 1 with a remainder of 500.
The next digit of our result is 1. 
Result so far: 81.0
The remainder is 500 after subtracting 680 from 1180.
Take the next digit (1) from the dividend and append it to 500, then repeat: 5001 / 680

On to step 6:
680 goes into 5001 7 times with a remainder of 241.
The number 7 becomes the next digit in our result. 
Result so far: 817.0
Deduct 4760 from 5001 and we're left with 241.
Include the next digit (3) from the dividend after 241, then repeat: 2413 / 680

Let's proceed to step 7:
The number 680 fits into 2413 3 times, leaving a remainder of 373.
The number 3 becomes the next digit in our result. 
Result so far: 8173.0
Deduct 2040 from 2413 and we're left with 373.
Append the next digit (9) from the dividend to 373 and continue with: 3739 / 680

Step 8:
680 goes into 3739 5 times with a remainder of 339.
Record the quotient 5 as the next digit in the result. 
Result so far: 81735.0
If we take 3400 away from 3739, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Advancing to step 9:
When dividing 3390 by 680, we get 4 with a remainder of 670.
Put 4 as the next digit of the answer. 
Result so far: 81735.4
Subtracting 2720 from 3390 leaves us with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 10:
6700 divided by 680 is 9 with a remainder of 580.
Record the quotient 9 as the next digit in the result. 
Result so far: 81735.49
If we subtract 6120 from 6700, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 11:
680 can be fit into 5800 8 times, resulting in a remainder of 360.
Record the quotient 8 as the next digit in the result. 
Result so far: 81735.498
Deduct 5440 from 5800 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 12:
680 can be fit into 3600 5 times, resulting in a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 81735.4985
If we take 3400 away from 3600, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 13:
The number 680 fits into 2000 2 times, leaving a remainder of 640.
Write down 2 as next digit of the result. 
Result so far: 81735.49852
The remainder is 640 after subtracting 1360 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 14:
When dividing 6400 by 680, we get 9 with a remainder of 280.
The number 9 becomes the next digit in our result. 
Result so far: 81735.498529
Subtract 6120 from 6400 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
680 goes into 2800 4 times with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 81735.4985294
Deduct 2720 from 2800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 16:
800 divided by 680 is 1 with a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 81735.49852941
Subtracting 680 from 800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 81735.49852941 with a balance of 1.2e-07.
