102930 divided by 86 
We're looking to find how many times 86 goes into 102930.

On to step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 86

On to step 2:
86 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 86

Moving on to step 3:
86 goes into 102 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 86 from 102 and we're left with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 86

Advancing to step 4:
The number 86 fits into 169 1 times, leaving a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 83 after subtracting 86 from 169.
Grab the next digit (3) from the dividend, add it to 83, then carry on: 833 / 86

Moving on to step 5:
If we divide 833 by 86, we get 9 and a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Subtract 774 from 833 to get 59.
Take the next digit (0) from the dividend and append it to 59, then repeat: 590 / 86

Going ahead to step 6:
590 divided by 86 is 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 1196.0
Deduct 516 from 590 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 7:
The number 86 fits into 740 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 1196.8
Subtract 688 from 740 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
86 can be fit into 520 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1196.86
Subtract 516 from 520 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
If we divide 40 by 86, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1196.86
Deduct 0 from 40 and we're left 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.

Moving on to step 10:
When dividing 400 by 86, we get 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 1196.8604
Deduct 344 from 400 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
86 goes into 560 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 1196.86046
Subtracting 516 from 560 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 1196.860465
Subtract 430 from 440 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
The number 86 fits into 100 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1196.8604651
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
86 goes into 140 1 times with a remainder of 54.
The next digit of our result is 1. 
Result so far: 1196.86046511
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 1196.86046511 and a remainder of 5.4e-08.
