86479434 ÷ 680 
We want to divide 86479434 by 680.

Step 1:
If we divide 8 by 680, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 680

Step 2:
680 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (4) from the dividend, add it to 86, then carry on: 864 / 680

Step 3:
680 can be fit into 864 1 times, resulting in a remainder of 184.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 680 away from 864, we end up with 184.
Grab the next digit (7) from the dividend, add it to 184, then carry on: 1847 / 680

Advancing to step 4:
680 can be fit into 1847 2 times, resulting in a remainder of 487.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1360 from 1847 and we're left with 487.
Bring next digit (9) of the dividend behind the 487 and repeat the process: 4879 / 680

Let's proceed to step 5:
When dividing 4879 by 680, we get 7 with a remainder of 119.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we subtract 4760 from 4879, we get 119.
Take the next digit (4) from the dividend and append it to 119, then repeat: 1194 / 680

Going ahead to step 6:
When dividing 1194 by 680, we get 1 with a remainder of 514.
Record the quotient 1 as the next digit in the result. 
Result so far: 1271.0
Subtract 680 from 1194 to get 514.
Take the next digit (3) from the dividend and append it to 514, then repeat: 5143 / 680

Step 7:
680 can be fit into 5143 7 times, resulting in a remainder of 383.
The next digit of our result is 7. 
Result so far: 12717.0
Deduct 4760 from 5143 and we're left with 383.
Grab the next digit (4) from the dividend, add it to 383, then carry on: 3834 / 680

Moving on to step 8:
680 goes into 3834 5 times with a remainder of 434.
The next digit of our result is 5. 
Result so far: 127175.0
If we subtract 3400 from 3834, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 9:
The number 680 fits into 4340 6 times, leaving a remainder of 260.
Use 6 as the next digit of our solution. 
Result so far: 127175.6
If we subtract 4080 from 4340, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 10:
The number 680 fits into 2600 3 times, leaving a remainder of 560.
Write down 3 as next digit of the result. 
Result so far: 127175.63
If we subtract 2040 from 2600, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 11:
If we divide 5600 by 680, we get 8 and a remainder of 160.
Put 8 as the next digit of the answer. 
Result so far: 127175.638
The remainder is 160 after subtracting 5440 from 5600.
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:
When dividing 1600 by 680, we get 2 with a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 127175.6382
If we take 1360 away from 1600, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 13:
680 can be fit into 2400 3 times, resulting in a remainder of 360.
Put 3 as the next digit of the answer. 
Result so far: 127175.63823
Subtract 2040 from 2400 to get 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 14:
3600 divided by 680 is 5 with a remainder of 200.
The next digit of our result is 5. 
Result so far: 127175.638235
If we subtract 3400 from 3600, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 15:
680 can be fit into 2000 2 times, resulting in a remainder of 640.
Put 2 as the next digit of the answer. 
Result so far: 127175.6382352
Deduct 1360 from 2000 and we're left with 640.
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 16:
6400 divided by 680 is 9 with a remainder of 280.
Put 9 as the next digit of the answer. 
Result so far: 127175.63823529
The remainder is 280 after subtracting 6120 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The quotient of the division is 127175.63823529, and the remainder is 2.8e-07.
