66973439 ÷ 106 
Let's see how many times 106 fits into 66973439.

On to step 1:
106 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 106

Advancing to step 2:
When dividing 66 by 106, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 106

Step 3:
When dividing 669 by 106, we get 6 with a remainder of 33.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 33 after subtracting 636 from 669.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 106

On to step 4:
The number 106 fits into 337 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 63.0
The remainder is 19 after subtracting 318 from 337.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 106

On to step 5:
The number 106 fits into 193 1 times, leaving a remainder of 87.
The number 1 becomes the next digit in our result. 
Result so far: 631.0
If we subtract 106 from 193, we get 87.
Append the next digit (4) from the dividend to 87 and continue with: 874 / 106

Moving on to step 6:
The number 106 fits into 874 8 times, leaving a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 6318.0
Subtracting 848 from 874 leaves us with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 106

Step 7:
106 can be fit into 263 2 times, resulting in a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 63182.0
If we take 212 away from 263, we end up with 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 106

Moving on to step 8:
When dividing 519 by 106, we get 4 with a remainder of 95.
Put 4 as the next digit of the answer. 
Result so far: 631824.0
Subtract 424 from 519 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 9:
106 goes into 950 8 times with a remainder of 102.
Write down 8 as next digit of the result. 
Result so far: 631824.8
If we take 848 away from 950, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 10:
If we divide 1020 by 106, we get 9 and a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 631824.89
The remainder is 66 after subtracting 954 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
If we divide 660 by 106, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 631824.896
Subtracting 636 from 660 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
106 goes into 240 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 631824.8962
Deduct 212 from 240 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
The number 106 fits into 280 2 times, leaving a remainder of 68.
The next digit of our result is 2. 
Result so far: 631824.89622
Subtracting 212 from 280 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 631824.89622, with a leftover of 6.8e-05.
