We're dividing 90317774 by 686 
We want to divide 90317774 by 686.

Step 1:
If we divide 9 by 686, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 686

Moving on to step 2:
90 divided by 686 is 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 686

Step 3:
686 goes into 903 1 times with a remainder of 217.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 686 from 903 and we're left with 217.
Fetch the next digit (1) from the dividend, attach it to 217 and continue: 2171 / 686

Going ahead to step 4:
686 can be fit into 2171 3 times, resulting in a remainder of 113.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 113 after subtracting 2058 from 2171.
Include the next digit (7) from the dividend after 113, then repeat: 1137 / 686

Step 5:
1137 divided by 686 is 1 with a remainder of 451.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtracting 686 from 1137 leaves us with 451.
Bring next digit (7) of the dividend behind the 451 and repeat the process: 4517 / 686

On to step 6:
If we divide 4517 by 686, we get 6 and a remainder of 401.
Put 6 as the next digit of the answer. 
Result so far: 1316.0
Subtract 4116 from 4517 to get 401.
Include the next digit (7) from the dividend after 401, then repeat: 4017 / 686

Moving on to step 7:
When dividing 4017 by 686, we get 5 with a remainder of 587.
Use 5 as the next digit of our solution. 
Result so far: 13165.0
If we subtract 3430 from 4017, we get 587.
Bring next digit (4) of the dividend behind the 587 and repeat the process: 5874 / 686

Let's proceed to step 8:
If we divide 5874 by 686, we get 8 and a remainder of 386.
Use 8 as the next digit of our solution. 
Result so far: 131658.0
Deduct 5488 from 5874 and we're left 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:
686 can be fit into 3860 5 times, resulting in a remainder of 430.
The number 5 becomes the next digit in our result. 
Result so far: 131658.5
Deduct 3430 from 3860 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 10:
If we divide 4300 by 686, we get 6 and a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 131658.56
Subtracting 4116 from 4300 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 11:
When dividing 1840 by 686, we get 2 with a remainder of 468.
The next digit of our result is 2. 
Result so far: 131658.562
The remainder is 468 after subtracting 1372 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 12:
The number 686 fits into 4680 6 times, leaving a remainder of 564.
Record the quotient 6 as the next digit in the result. 
Result so far: 131658.5626
Subtract 4116 from 4680 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 13:
When dividing 5640 by 686, we get 8 with a remainder of 152.
The next digit of our result is 8. 
Result so far: 131658.56268
If we take 5488 away from 5640, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 14:
The number 686 fits into 1520 2 times, leaving a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 131658.562682
If we subtract 1372 from 1520, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 15:
1480 divided by 686 is 2 with a remainder of 108.
Put 2 as the next digit of the answer. 
Result so far: 131658.5626822
Subtracting 1372 from 1480 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 131658.5626822, with a leftover of 1.08e-06.
