948 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 948

Advancing to step 2:
948 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 948

Advancing to step 3:
948 can be fit into 810 0 times, resulting in a remainder of 810.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 810 after subtracting 0 from 810.
Take the next digit (0) from the dividend and append it to 810, then repeat: 8100 / 948

On to step 4:
8100 divided by 948 is 8 with a remainder of 516.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 7584 from 8100 and we're left with 516.
Bring next digit (4) of the dividend behind the 516 and repeat the process: 5164 / 948

Moving on to step 5:
When dividing 5164 by 948, we get 5 with a remainder of 424.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Subtract 4740 from 5164 to get 424.
Append the next digit (2) from the dividend to 424 and continue with: 4242 / 948

Advancing to step 6:
If we divide 4242 by 948, we get 4 and a remainder of 450.
Use 4 as the next digit of our solution. 
Result so far: 854.0
Subtract 3792 from 4242 to get 450.
Bring next digit (9) of the dividend behind the 450 and repeat the process: 4509 / 948

Advancing to step 7:
The number 948 fits into 4509 4 times, leaving a remainder of 717.
The number 4 becomes the next digit in our result. 
Result so far: 8544.0
If we subtract 3792 from 4509, we get 717.
Append the next digit (0) from the dividend to 717 and continue with: 7170 / 948

Step 8:
When dividing 7170 by 948, we get 7 with a remainder of 534.
Write down 7 as next digit of the result. 
Result so far: 85447.0
Subtract 6636 from 7170 to get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Moving on to step 9:
The number 948 fits into 5340 5 times, leaving a remainder of 600.
Record the quotient 5 as the next digit in the result. 
Result so far: 85447.5
Deduct 4740 from 5340 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 10:
If we divide 6000 by 948, we get 6 and a remainder of 312.
The next digit of our result is 6. 
Result so far: 85447.56
Subtracting 5688 from 6000 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 11:
The number 948 fits into 3120 3 times, leaving a remainder of 276.
The number 3 becomes the next digit in our result. 
Result so far: 85447.563
The remainder is 276 after subtracting 2844 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 12:
948 can be fit into 2760 2 times, resulting in a remainder of 864.
Put 2 as the next digit of the answer. 
Result so far: 85447.5632
Subtract 1896 from 2760 to get 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Step 13:
948 goes into 8640 9 times with a remainder of 108.
The number 9 becomes the next digit in our result. 
Result so far: 85447.56329
Subtracting 8532 from 8640 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 14:
1080 divided by 948 is 1 with a remainder of 132.
Write down 1 as next digit of the result. 
Result so far: 85447.563291
If we subtract 948 from 1080, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 15:
948 goes into 1320 1 times with a remainder of 372.
Write down 1 as next digit of the result. 
Result so far: 85447.5632911
If we take 948 away from 1320, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Our division results in 85447.5632911 with a remaining 3.72e-06.
