89390676 ÷ 664 
Our goal is to divide 89390676 by 664.

Step 1:
8 divided by 664 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 664

Moving on to step 2:
If we divide 89 by 664, we get 0 and a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Take the next digit (3) from the dividend and append it to 89, then repeat: 893 / 664

Going ahead to step 3:
893 divided by 664 is 1 with a remainder of 229.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 664 away from 893, we end up with 229.
Include the next digit (9) from the dividend after 229, then repeat: 2299 / 664

Step 4:
2299 divided by 664 is 3 with a remainder of 307.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 307 after subtracting 1992 from 2299.
Take the next digit (0) from the dividend and append it to 307, then repeat: 3070 / 664

Step 5:
664 can be fit into 3070 4 times, resulting in a remainder of 414.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Deduct 2656 from 3070 and we're left with 414.
Fetch the next digit (6) from the dividend, attach it to 414 and continue: 4146 / 664

Let's proceed to step 6:
4146 divided by 664 is 6 with a remainder of 162.
Put 6 as the next digit of the answer. 
Result so far: 1346.0
Deduct 3984 from 4146 and we're left with 162.
Grab the next digit (7) from the dividend, add it to 162, then carry on: 1627 / 664

Advancing to step 7:
1627 divided by 664 is 2 with a remainder of 299.
Write down 2 as next digit of the result. 
Result so far: 13462.0
If we take 1328 away from 1627, we end up with 299.
Take the next digit (6) from the dividend and append it to 299, then repeat: 2996 / 664

Advancing to step 8:
664 can be fit into 2996 4 times, resulting in a remainder of 340.
Put 4 as the next digit of the answer. 
Result so far: 134624.0
Deduct 2656 from 2996 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 9:
3400 divided by 664 is 5 with a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 134624.5
Subtracting 3320 from 3400 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
If we divide 800 by 664, we get 1 and a remainder of 136.
The next digit of our result is 1. 
Result so far: 134624.51
If we subtract 664 from 800, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 11:
1360 divided by 664 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 134624.512
If we subtract 1328 from 1360, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
If we divide 320 by 664, we get 0 and a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 134624.512
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
If we divide 3200 by 664, we get 4 and a remainder of 544.
Put 4 as the next digit of the answer. 
Result so far: 134624.51204
Subtract 2656 from 3200 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 14:
664 can be fit into 5440 8 times, resulting in a remainder of 128.
The next digit of our result is 8. 
Result so far: 134624.512048
The remainder is 128 after subtracting 5312 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 15:
664 can be fit into 1280 1 times, resulting in a remainder of 616.
Record the quotient 1 as the next digit in the result. 
Result so far: 134624.5120481
If we take 664 away from 1280, we end up with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Going ahead to step 16:
The number 664 fits into 6160 9 times, leaving a remainder of 184.
Write down 9 as next digit of the result. 
Result so far: 134624.51204819
Subtract 5976 from 6160 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The quotient of the division is 134624.51204819, and the remainder is 1.84e-07.
