86099247 divided by 671 
We want to figure out the number of times 86099247 can be divided by 671.

Step 1:
671 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 671

On to step 2:
The number 671 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (0) from the dividend after 86, then repeat: 860 / 671

Going ahead to step 3:
671 goes into 860 1 times with a remainder of 189.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 671 from 860, we get 189.
Fetch the next digit (9) from the dividend, attach it to 189 and continue: 1899 / 671

Step 4:
If we divide 1899 by 671, we get 2 and a remainder of 557.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 1342 from 1899 leaves us with 557.
Bring next digit (9) of the dividend behind the 557 and repeat the process: 5579 / 671

Going ahead to step 5:
When dividing 5579 by 671, we get 8 with a remainder of 211.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Subtract 5368 from 5579 to get 211.
Grab the next digit (2) from the dividend, add it to 211, then carry on: 2112 / 671

Step 6:
The number 671 fits into 2112 3 times, leaving a remainder of 99.
The number 3 becomes the next digit in our result. 
Result so far: 1283.0
If we subtract 2013 from 2112, we get 99.
Append the next digit (4) from the dividend to 99 and continue with: 994 / 671

Moving on to step 7:
671 goes into 994 1 times with a remainder of 323.
Write down 1 as next digit of the result. 
Result so far: 12831.0
Subtracting 671 from 994 leaves us with 323.
Take the next digit (7) from the dividend and append it to 323, then repeat: 3237 / 671

Moving on to step 8:
671 can be fit into 3237 4 times, resulting in a remainder of 553.
The next digit of our result is 4. 
Result so far: 128314.0
Subtracting 2684 from 3237 leaves us with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 9:
5530 divided by 671 is 8 with a remainder of 162.
The next digit of our result is 8. 
Result so far: 128314.8
If we subtract 5368 from 5530, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 10:
When dividing 1620 by 671, we get 2 with a remainder of 278.
The next digit of our result is 2. 
Result so far: 128314.82
If we subtract 1342 from 1620, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 11:
671 goes into 2780 4 times with a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 128314.824
Subtract 2684 from 2780 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 12:
960 divided by 671 is 1 with a remainder of 289.
Record the quotient 1 as the next digit in the result. 
Result so far: 128314.8241
Deduct 671 from 960 and we're left with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

On to step 13:
671 goes into 2890 4 times with a remainder of 206.
Write down 4 as next digit of the result. 
Result so far: 128314.82414
If we take 2684 away from 2890, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 14:
The number 671 fits into 2060 3 times, leaving a remainder of 47.
The next digit of our result is 3. 
Result so far: 128314.824143
If we take 2013 away from 2060, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 15:
671 goes into 470 0 times with a remainder of 470.
Put 0 as the next digit of the answer. 
Result so far: 128314.824143
Deduct 0 from 470 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 16:
671 can be fit into 4700 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 128314.82414307
If we take 4697 away from 4700, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 128314.82414307, with a leftover of 3e-09.
