66816931 divided by 154 
Our goal is to divide 66816931 by 154.

Advancing to step 1:
6 divided by 154 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 154

Moving on to step 2:
If we divide 66 by 154, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 154

Going ahead to step 3:
If we divide 668 by 154, we get 4 and a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 52 after subtracting 616 from 668.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 154

Going ahead to step 4:
154 can be fit into 521 3 times, resulting in a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we subtract 462 from 521, we get 59.
Fetch the next digit (6) from the dividend, attach it to 59 and continue: 596 / 154

Advancing to step 5:
154 can be fit into 596 3 times, resulting in a remainder of 134.
Record the quotient 3 as the next digit in the result. 
Result so far: 433.0
If we subtract 462 from 596, we get 134.
Fetch the next digit (9) from the dividend, attach it to 134 and continue: 1349 / 154

Let's proceed to step 6:
If we divide 1349 by 154, we get 8 and a remainder of 117.
Write down 8 as next digit of the result. 
Result so far: 4338.0
Subtract 1232 from 1349 to get 117.
Include the next digit (3) from the dividend after 117, then repeat: 1173 / 154

On to step 7:
154 can be fit into 1173 7 times, resulting in a remainder of 95.
Put 7 as the next digit of the answer. 
Result so far: 43387.0
If we subtract 1078 from 1173, we get 95.
Append the next digit (1) from the dividend to 95 and continue with: 951 / 154

Going ahead to step 8:
154 goes into 951 6 times with a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 433876.0
Subtracting 924 from 951 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
If we divide 270 by 154, we get 1 and a remainder of 116.
Put 1 as the next digit of the answer. 
Result so far: 433876.1
The remainder is 116 after subtracting 154 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 10:
154 goes into 1160 7 times with a remainder of 82.
Write down 7 as next digit of the result. 
Result so far: 433876.17
Deduct 1078 from 1160 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 11:
154 can be fit into 820 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 433876.175
If we subtract 770 from 820, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
When dividing 500 by 154, we get 3 with a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 433876.1753
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
When dividing 380 by 154, we get 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 433876.17532
If we take 308 away from 380, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
If we divide 720 by 154, we get 4 and a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 433876.175324
Subtracting 616 from 720 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 15:
If we divide 1040 by 154, we get 6 and a remainder of 116.
Put 6 as the next digit of the answer. 
Result so far: 433876.1753246
If we subtract 924 from 1040, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 16:
When dividing 1160 by 154, we get 7 with a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 433876.17532467
Subtract 1078 from 1160 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

The quotient of the division is 433876.17532467, and the remainder is 8.2e-08.
