We divide 15729891 by 680
We want to divide 15729891 by 680.

On to step 1:
1 divided by 680 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 680

Advancing to step 2:
When dividing 15 by 680, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 680

Step 3:
If we divide 157 by 680, we get 0 and a remainder of 157.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 157 after subtracting 0 from 157.
Grab the next digit (2) from the dividend, add it to 157, then carry on: 1572 / 680

Going ahead to step 4:
The number 680 fits into 1572 2 times, leaving a remainder of 212.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1360 from 1572 to get 212.
Bring next digit (9) of the dividend behind the 212 and repeat the process: 2129 / 680

Going ahead to step 5:
If we divide 2129 by 680, we get 3 and a remainder of 89.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 2040 from 2129, we get 89.
Fetch the next digit (8) from the dividend, attach it to 89 and continue: 898 / 680

Going ahead to step 6:
898 divided by 680 is 1 with a remainder of 218.
Record the quotient 1 as the next digit in the result. 
Result so far: 231.0
If we take 680 away from 898, we end up with 218.
Fetch the next digit (9) from the dividend, attach it to 218 and continue: 2189 / 680

Step 7:
2189 divided by 680 is 3 with a remainder of 149.
The number 3 becomes the next digit in our result. 
Result so far: 2313.0
If we take 2040 away from 2189, we end up with 149.
Take the next digit (1) from the dividend and append it to 149, then repeat: 1491 / 680

Let's proceed to step 8:
If we divide 1491 by 680, we get 2 and a remainder of 131.
The next digit of our result is 2. 
Result so far: 23132.0
The remainder is 131 after subtracting 1360 from 1491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 9:
680 goes into 1310 1 times with a remainder of 630.
The number 1 becomes the next digit in our result. 
Result so far: 23132.1
Subtracting 680 from 1310 leaves us 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.

Step 10:
When dividing 6300 by 680, we get 9 with a remainder of 180.
Use 9 as the next digit of our solution. 
Result so far: 23132.19
Subtract 6120 from 6300 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 11:
If we divide 1800 by 680, we get 2 and a remainder of 440.
Record the quotient 2 as the next digit in the result. 
Result so far: 23132.192
If we subtract 1360 from 1800, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 12:
When dividing 4400 by 680, we get 6 with a remainder of 320.
Write down 6 as next digit of the result. 
Result so far: 23132.1926
If we take 4080 away from 4400, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
The number 680 fits into 3200 4 times, leaving a remainder of 480.
Write down 4 as next digit of the result. 
Result so far: 23132.19264
If we take 2720 away from 3200, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 14:
680 goes into 4800 7 times with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 23132.192647
The remainder is 40 after subtracting 4760 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 15:
When dividing 400 by 680, we get 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 23132.192647
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 16:
4000 divided by 680 is 5 with a remainder of 600.
The next digit of our result is 5. 
Result so far: 23132.19264705
Subtract 3400 from 4000 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

In conclusion, the division gives 23132.19264705 with a balance of 6e-07.
