We look at the division of 33561921 by 686 
We're looking to find how many times 686 goes into 33561921.

Step 1:
686 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 686

Moving on to step 2:
When dividing 33 by 686, we get 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Fetch the next digit (5) from the dividend, attach it to 33 and continue: 335 / 686

Moving on to step 3:
686 goes into 335 0 times with a remainder of 335.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 335, we get 335.
Append the next digit (6) from the dividend to 335 and continue with: 3356 / 686

Advancing to step 4:
686 goes into 3356 4 times with a remainder of 612.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 2744 away from 3356, we end up with 612.
Fetch the next digit (1) from the dividend, attach it to 612 and continue: 6121 / 686

Moving on to step 5:
If we divide 6121 by 686, we get 8 and a remainder of 633.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Deduct 5488 from 6121 and we're left with 633.
Bring next digit (9) of the dividend behind the 633 and repeat the process: 6339 / 686

Step 6:
The number 686 fits into 6339 9 times, leaving a remainder of 165.
The number 9 becomes the next digit in our result. 
Result so far: 489.0
Deduct 6174 from 6339 and we're left with 165.
Fetch the next digit (2) from the dividend, attach it to 165 and continue: 1652 / 686

Advancing to step 7:
686 goes into 1652 2 times with a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 4892.0
If we take 1372 away from 1652, we end up with 280.
Include the next digit (1) from the dividend after 280, then repeat: 2801 / 686

On to step 8:
The number 686 fits into 2801 4 times, leaving a remainder of 57.
The next digit of our result is 4. 
Result so far: 48924.0
If we subtract 2744 from 2801, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 9:
The number 686 fits into 570 0 times, leaving a remainder of 570.
The number 0 becomes the next digit in our result. 
Result so far: 48924.0
If we take 0 away from 570, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Moving on to step 10:
The number 686 fits into 5700 8 times, leaving a remainder of 212.
Put 8 as the next digit of the answer. 
Result so far: 48924.08
If we take 5488 away from 5700, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 11:
686 goes into 2120 3 times with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 48924.083
Subtracting 2058 from 2120 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 12:
686 goes into 620 0 times with a remainder of 620.
The next digit of our result is 0. 
Result so far: 48924.083
Deduct 0 from 620 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 13:
If we divide 6200 by 686, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 48924.08309
If we take 6174 away from 6200, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
If we divide 260 by 686, we get 0 and a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 48924.08309
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 15:
If we divide 2600 by 686, we get 3 and a remainder of 542.
The number 3 becomes the next digit in our result. 
Result so far: 48924.0830903
Subtract 2058 from 2600 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Step 16:
686 goes into 5420 7 times with a remainder of 618.
Write down 7 as next digit of the result. 
Result so far: 48924.08309037
Subtracting 4802 from 5420 leaves us with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

The final outcome is 48924.08309037, with a leftover of 6.18e-07.
