66806386 ÷ 146 
Our goal is to divide 66806386 by 146.

Advancing to step 1:
The number 146 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 146

Going ahead to step 2:
The number 146 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 146

Step 3:
When dividing 668 by 146, we get 4 with a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 584 away from 668, we end up with 84.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 146

Step 4:
If we divide 840 by 146, we get 5 and a remainder of 110.
The next digit of our result is 5. 
Result so far: 45.0
If we take 730 away from 840, we end up with 110.
Take the next digit (6) from the dividend and append it to 110, then repeat: 1106 / 146

Advancing to step 5:
The number 146 fits into 1106 7 times, leaving a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 457.0
If we subtract 1022 from 1106, we get 84.
Include the next digit (3) from the dividend after 84, then repeat: 843 / 146

Let's proceed to step 6:
When dividing 843 by 146, we get 5 with a remainder of 113.
The next digit of our result is 5. 
Result so far: 4575.0
Subtract 730 from 843 to get 113.
Bring next digit (8) of the dividend behind the 113 and repeat the process: 1138 / 146

Step 7:
1138 divided by 146 is 7 with a remainder of 116.
Record the quotient 7 as the next digit in the result. 
Result so far: 45757.0
If we take 1022 away from 1138, we end up with 116.
Grab the next digit (6) from the dividend, add it to 116, then carry on: 1166 / 146

Step 8:
1166 divided by 146 is 7 with a remainder of 144.
Use 7 as the next digit of our solution. 
Result so far: 457577.0
If we subtract 1022 from 1166, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 9:
146 can be fit into 1440 9 times, resulting in a remainder of 126.
The next digit of our result is 9. 
Result so far: 457577.9
Subtracting 1314 from 1440 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 10:
1260 divided by 146 is 8 with a remainder of 92.
Use 8 as the next digit of our solution. 
Result so far: 457577.98
If we take 1168 away from 1260, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 11:
920 divided by 146 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 457577.986
If we subtract 876 from 920, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
146 goes into 440 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 457577.9863
The remainder is 2 after subtracting 438 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
When dividing 20 by 146, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 457577.9863
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
200 divided by 146 is 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 457577.986301
If we take 146 away from 200, we end up 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.

Moving on to step 15:
When dividing 540 by 146, we get 3 with a remainder of 102.
The number 3 becomes the next digit in our result. 
Result so far: 457577.9863013
The remainder is 102 after subtracting 438 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 16:
1020 divided by 146 is 6 with a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 457577.98630136
Subtracting 876 from 1020 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

After the division, we end up with 457577.98630136 and a remainder of 1.44e-07.
