51081565 ÷ 681 
We're looking to find how many times 681 goes into 51081565.

On to step 1:
If we divide 5 by 681, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 681

Going ahead to step 2:
When dividing 51 by 681, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 681

Going ahead to step 3:
If we divide 510 by 681, we get 0 and a remainder of 510.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 510, we get 510.
Grab the next digit (8) from the dividend, add it to 510, then carry on: 5108 / 681

Moving on to step 4:
The number 681 fits into 5108 7 times, leaving a remainder of 341.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 4767 from 5108 leaves us with 341.
Append the next digit (1) from the dividend to 341 and continue with: 3411 / 681

Let's proceed to step 5:
3411 divided by 681 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtract 3405 from 3411 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 681

Going ahead to step 6:
The number 681 fits into 65 0 times, leaving a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 750.0
Subtracting 0 from 65 leaves us with 65.
Append the next digit (6) from the dividend to 65 and continue with: 656 / 681

Advancing to step 7:
If we divide 656 by 681, we get 0 and a remainder of 656.
Write down 0 as next digit of the result. 
Result so far: 7500.0
Subtract 0 from 656 to get 656.
Take the next digit (5) from the dividend and append it to 656, then repeat: 6565 / 681

Advancing to step 8:
When dividing 6565 by 681, we get 9 with a remainder of 436.
Use 9 as the next digit of our solution. 
Result so far: 75009.0
Subtract 6129 from 6565 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 9:
The number 681 fits into 4360 6 times, leaving a remainder of 274.
The next digit of our result is 6. 
Result so far: 75009.6
The remainder is 274 after subtracting 4086 from 4360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 10:
681 can be fit into 2740 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 75009.64
The remainder is 16 after subtracting 2724 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 681 fits into 160 0 times, leaving a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 75009.64
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
681 can be fit into 1600 2 times, resulting in a remainder of 238.
Use 2 as the next digit of our solution. 
Result so far: 75009.6402
Subtract 1362 from 1600 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 13:
If we divide 2380 by 681, we get 3 and a remainder of 337.
Put 3 as the next digit of the answer. 
Result so far: 75009.64023
If we take 2043 away from 2380, we end up with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Let's proceed to step 14:
681 goes into 3370 4 times with a remainder of 646.
The number 4 becomes the next digit in our result. 
Result so far: 75009.640234
If we take 2724 away from 3370, we end up with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Moving on to step 15:
6460 divided by 681 is 9 with a remainder of 331.
The number 9 becomes the next digit in our result. 
Result so far: 75009.6402349
If we take 6129 away from 6460, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 16:
681 can be fit into 3310 4 times, resulting in a remainder of 586.
Write down 4 as next digit of the result. 
Result so far: 75009.64023494
If we take 2724 away from 3310, we end up with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

In conclusion, the division gives 75009.64023494 with a balance of 5.86e-07.
