86845906 ÷ 680 
Let's see how many times 680 fits into 86845906.

Step 1:
680 goes into 8 0 times with 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.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 680

Advancing to 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
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (8) from the dividend, add it to 86, then carry on: 868 / 680

Advancing to step 3:
680 can be fit into 868 1 times, resulting in a remainder of 188.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 680 from 868 to get 188.
Bring next digit (4) of the dividend behind the 188 and repeat the process: 1884 / 680

Step 4:
680 goes into 1884 2 times with a remainder of 524.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 1360 from 1884 to get 524.
Include the next digit (5) from the dividend after 524, then repeat: 5245 / 680

Let's proceed to step 5:
The number 680 fits into 5245 7 times, leaving a remainder of 485.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
If we subtract 4760 from 5245, we get 485.
Take the next digit (9) from the dividend and append it to 485, then repeat: 4859 / 680

Going ahead to step 6:
When dividing 4859 by 680, we get 7 with a remainder of 99.
Write down 7 as next digit of the result. 
Result so far: 1277.0
If we subtract 4760 from 4859, we get 99.
Append the next digit (0) from the dividend to 99 and continue with: 990 / 680

Going ahead to step 7:
680 goes into 990 1 times with a remainder of 310.
The next digit of our result is 1. 
Result so far: 12771.0
Deduct 680 from 990 and we're left with 310.
Include the next digit (6) from the dividend after 310, then repeat: 3106 / 680

Let's proceed to step 8:
When dividing 3106 by 680, we get 4 with a remainder of 386.
Put 4 as the next digit of the answer. 
Result so far: 127714.0
Subtracting 2720 from 3106 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 9:
The number 680 fits into 3860 5 times, leaving a remainder of 460.
Use 5 as the next digit of our solution. 
Result so far: 127714.5
If we subtract 3400 from 3860, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 10:
4600 divided by 680 is 6 with a remainder of 520.
The number 6 becomes the next digit in our result. 
Result so far: 127714.56
If we take 4080 away from 4600, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 11:
680 goes into 5200 7 times with a remainder of 440.
Write down 7 as next digit of the result. 
Result so far: 127714.567
The remainder is 440 after subtracting 4760 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 12:
680 can be fit into 4400 6 times, resulting in a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 127714.5676
The remainder is 320 after subtracting 4080 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 13:
When dividing 3200 by 680, we get 4 with a remainder of 480.
Put 4 as the next digit of the answer. 
Result so far: 127714.56764
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.

Let's proceed to step 14:
680 can be fit into 4800 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 127714.567647
Subtracting 4760 from 4800 leaves us with 40.
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:
If we divide 400 by 680, we get 0 and a remainder of 400.
The next digit of our result is 0. 
Result so far: 127714.567647
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 16:
680 goes into 4000 5 times with a remainder of 600.
The next digit of our result is 5. 
Result so far: 127714.56764705
Deduct 3400 from 4000 and we're left with 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 127714.56764705 with a balance of 6e-07.
