80674131 ÷ 664 
Let's see how many times 664 fits into 80674131.

Advancing to step 1:
The number 664 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 664

Going ahead to step 2:
If we divide 80 by 664, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 664

Advancing to step 3:
When dividing 806 by 664, we get 1 with a remainder of 142.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 664 from 806, we get 142.
Append the next digit (7) from the dividend to 142 and continue with: 1427 / 664

On to step 4:
664 can be fit into 1427 2 times, resulting in a remainder of 99.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1328 from 1427, we get 99.
Fetch the next digit (4) from the dividend, attach it to 99 and continue: 994 / 664

Step 5:
If we divide 994 by 664, we get 1 and a remainder of 330.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
If we take 664 away from 994, we end up with 330.
Take the next digit (1) from the dividend and append it to 330, then repeat: 3301 / 664

Moving on to step 6:
When dividing 3301 by 664, we get 4 with a remainder of 645.
The number 4 becomes the next digit in our result. 
Result so far: 1214.0
If we take 2656 away from 3301, we end up with 645.
Grab the next digit (3) from the dividend, add it to 645, then carry on: 6453 / 664

Let's proceed to step 7:
664 can be fit into 6453 9 times, resulting in a remainder of 477.
Write down 9 as next digit of the result. 
Result so far: 12149.0
Subtracting 5976 from 6453 leaves us with 477.
Fetch the next digit (1) from the dividend, attach it to 477 and continue: 4771 / 664

Going ahead to step 8:
The number 664 fits into 4771 7 times, leaving a remainder of 123.
Put 7 as the next digit of the answer. 
Result so far: 121497.0
Deduct 4648 from 4771 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 9:
664 can be fit into 1230 1 times, resulting in a remainder of 566.
Use 1 as the next digit of our solution. 
Result so far: 121497.1
If we subtract 664 from 1230, we get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Going ahead to step 10:
If we divide 5660 by 664, we get 8 and a remainder of 348.
The number 8 becomes the next digit in our result. 
Result so far: 121497.18
Deduct 5312 from 5660 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 11:
When dividing 3480 by 664, we get 5 with a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 121497.185
Subtracting 3320 from 3480 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
664 goes into 1600 2 times with a remainder of 272.
Record the quotient 2 as the next digit in the result. 
Result so far: 121497.1852
If we subtract 1328 from 1600, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 13:
664 can be fit into 2720 4 times, resulting in a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 121497.18524
The remainder is 64 after subtracting 2656 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
664 can be fit into 640 0 times, resulting in a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 121497.18524
The remainder is 640 after subtracting 0 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 15:
The number 664 fits into 6400 9 times, leaving a remainder of 424.
Write down 9 as next digit of the result. 
Result so far: 121497.1852409
Subtract 5976 from 6400 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 16:
If we divide 4240 by 664, we get 6 and a remainder of 256.
The next digit of our result is 6. 
Result so far: 121497.18524096
If we subtract 3984 from 4240, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Our division results in 121497.18524096 with a remaining 2.56e-07.
