If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 912

On to step 2:
912 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 912

Step 3:
If we divide 669 by 912, we get 0 and a remainder of 669.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 669, we get 669.
Take the next digit (6) from the dividend and append it to 669, then repeat: 6696 / 912

Going ahead to step 4:
912 goes into 6696 7 times with a remainder of 312.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 6384 from 6696 and we're left with 312.
Fetch the next digit (0) from the dividend, attach it to 312 and continue: 3120 / 912

Advancing to step 5:
912 goes into 3120 3 times with a remainder of 384.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
If we take 2736 away from 3120, we end up with 384.
Take the next digit (5) from the dividend and append it to 384, then repeat: 3845 / 912

Going ahead to step 6:
The number 912 fits into 3845 4 times, leaving a remainder of 197.
Use 4 as the next digit of our solution. 
Result so far: 734.0
Subtracting 3648 from 3845 leaves us with 197.
Fetch the next digit (9) from the dividend, attach it to 197 and continue: 1979 / 912

Let's proceed to step 7:
The number 912 fits into 1979 2 times, leaving a remainder of 155.
Use 2 as the next digit of our solution. 
Result so far: 7342.0
Subtract 1824 from 1979 to get 155.
Include the next digit (2) from the dividend after 155, then repeat: 1552 / 912

Let's proceed to step 8:
1552 divided by 912 is 1 with a remainder of 640.
The number 1 becomes the next digit in our result. 
Result so far: 73421.0
If we subtract 912 from 1552, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 9:
6400 divided by 912 is 7 with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 73421.7
Deduct 6384 from 6400 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
912 can be fit into 160 0 times, resulting in a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 73421.7
Deduct 0 from 160 and we're left 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.

Going ahead to step 11:
The number 912 fits into 1600 1 times, leaving a remainder of 688.
Use 1 as the next digit of our solution. 
Result so far: 73421.701
Subtract 912 from 1600 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

On to step 12:
When dividing 6880 by 912, we get 7 with a remainder of 496.
The number 7 becomes the next digit in our result. 
Result so far: 73421.7017
Deduct 6384 from 6880 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 13:
912 can be fit into 4960 5 times, resulting in a remainder of 400.
Write down 5 as next digit of the result. 
Result so far: 73421.70175
The remainder is 400 after subtracting 4560 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 14:
The number 912 fits into 4000 4 times, leaving a remainder of 352.
The number 4 becomes the next digit in our result. 
Result so far: 73421.701754
Deduct 3648 from 4000 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 15:
912 can be fit into 3520 3 times, resulting in a remainder of 784.
The next digit of our result is 3. 
Result so far: 73421.7017543
If we take 2736 away from 3520, we end up with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Step 16:
When dividing 7840 by 912, we get 8 with a remainder of 544.
The number 8 becomes the next digit in our result. 
Result so far: 73421.70175438
Subtract 7296 from 7840 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.

The final result is 73421.70175438 with a remainder of 5.44e-07.
