We're dividing 54021312 by 946 
Our goal is to divide 54021312 by 946.

Step 1:
5 divided by 946 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 946

Step 2:
946 can be fit into 54 0 times, resulting in a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Take the next digit (0) from the dividend and append it to 54, then repeat: 540 / 946

Advancing to step 3:
540 divided by 946 is 0 with a remainder of 540.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 540 to get 540.
Append the next digit (2) from the dividend to 540 and continue with: 5402 / 946

Advancing to step 4:
946 can be fit into 5402 5 times, resulting in a remainder of 672.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 4730 from 5402 to get 672.
Take the next digit (1) from the dividend and append it to 672, then repeat: 6721 / 946

Let's proceed to step 5:
The number 946 fits into 6721 7 times, leaving a remainder of 99.
The next digit of our result is 7. 
Result so far: 57.0
Deduct 6622 from 6721 and we're left with 99.
Fetch the next digit (3) from the dividend, attach it to 99 and continue: 993 / 946

Step 6:
946 goes into 993 1 times with a remainder of 47.
The next digit of our result is 1. 
Result so far: 571.0
If we subtract 946 from 993, we get 47.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 946

Going ahead to step 7:
946 goes into 471 0 times with a remainder of 471.
Use 0 as the next digit of our solution. 
Result so far: 5710.0
Subtract 0 from 471 to get 471.
Fetch the next digit (2) from the dividend, attach it to 471 and continue: 4712 / 946

Moving on to step 8:
When dividing 4712 by 946, we get 4 with a remainder of 928.
The number 4 becomes the next digit in our result. 
Result so far: 57104.0
Subtracting 3784 from 4712 leaves us with 928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9280, and continue the process.

Let's proceed to step 9:
946 goes into 9280 9 times with a remainder of 766.
Write down 9 as next digit of the result. 
Result so far: 57104.9
The remainder is 766 after subtracting 8514 from 9280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Step 10:
946 goes into 7660 8 times with a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 57104.98
Subtracting 7568 from 7660 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 11:
When dividing 920 by 946, we get 0 with a remainder of 920.
Record the quotient 0 as the next digit in the result. 
Result so far: 57104.98
Deduct 0 from 920 and we're left with 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

Let's proceed to step 12:
If we divide 9200 by 946, we get 9 and a remainder of 686.
Record the quotient 9 as the next digit in the result. 
Result so far: 57104.9809
Subtracting 8514 from 9200 leaves us with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

On to step 13:
If we divide 6860 by 946, we get 7 and a remainder of 238.
Use 7 as the next digit of our solution. 
Result so far: 57104.98097
The remainder is 238 after subtracting 6622 from 6860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 14:
When dividing 2380 by 946, we get 2 with a remainder of 488.
Record the quotient 2 as the next digit in the result. 
Result so far: 57104.980972
Deduct 1892 from 2380 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 15:
When dividing 4880 by 946, we get 5 with a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 57104.9809725
The remainder is 150 after subtracting 4730 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 16:
When dividing 1500 by 946, we get 1 with a remainder of 554.
The number 1 becomes the next digit in our result. 
Result so far: 57104.98097251
If we take 946 away from 1500, we end up with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

The quotient of the division is 57104.98097251, and the remainder is 5.54e-07.
