66469804 ÷ 138 
We want to divide 66469804 by 138.

Step 1:
138 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 138

Advancing to step 2:
The number 138 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 138

Moving on to step 3:
When dividing 664 by 138, we get 4 with a remainder of 112.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 552 from 664 to get 112.
Grab the next digit (6) from the dividend, add it to 112, then carry on: 1126 / 138

On to step 4:
1126 divided by 138 is 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 48.0
The remainder is 22 after subtracting 1104 from 1126.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 138

Going ahead to step 5:
138 goes into 229 1 times with a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 481.0
If we take 138 away from 229, we end up with 91.
Grab the next digit (8) from the dividend, add it to 91, then carry on: 918 / 138

Step 6:
138 goes into 918 6 times with a remainder of 90.
The next digit of our result is 6. 
Result so far: 4816.0
If we subtract 828 from 918, we get 90.
Fetch the next digit (0) from the dividend, attach it to 90 and continue: 900 / 138

Advancing to step 7:
138 can be fit into 900 6 times, resulting in a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 48166.0
If we take 828 away from 900, we end up with 72.
Append the next digit (4) from the dividend to 72 and continue with: 724 / 138

Moving on to step 8:
When dividing 724 by 138, we get 5 with a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 481665.0
Subtracting 690 from 724 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
When dividing 340 by 138, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 481665.2
Deduct 276 from 340 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
138 goes into 640 4 times with a remainder of 88.
The next digit of our result is 4. 
Result so far: 481665.24
Deduct 552 from 640 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 11:
138 goes into 880 6 times with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 481665.246
Subtracting 828 from 880 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
520 divided by 138 is 3 with a remainder of 106.
Use 3 as the next digit of our solution. 
Result so far: 481665.2463
Subtract 414 from 520 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 13:
138 can be fit into 1060 7 times, resulting in a remainder of 94.
Put 7 as the next digit of the answer. 
Result so far: 481665.24637
If we subtract 966 from 1060, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 14:
The number 138 fits into 940 6 times, leaving a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 481665.246376
Subtracting 828 from 940 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 15:
When dividing 1120 by 138, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 481665.2463768
The remainder is 16 after subtracting 1104 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 16:
138 goes into 160 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 481665.24637681
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 481665.24637681 with a remaining 2.2e-08.
