943139 ÷ 48 
Our goal is to divide 943139 by 48.

Let's proceed to step 1:
When dividing 9 by 48, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 48

On to step 2:
48 goes into 94 1 times with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 48 from 94 to get 46.
Take the next digit (3) from the dividend and append it to 46, then repeat: 463 / 48

Let's proceed to step 3:
When dividing 463 by 48, we get 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 432 from 463 and we're left with 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 48

Going ahead to step 4:
The number 48 fits into 311 6 times, leaving a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 196.0
If we subtract 288 from 311, we get 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 48

Going ahead to step 5:
If we divide 233 by 48, we get 4 and a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 1964.0
The remainder is 41 after subtracting 192 from 233.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 48

Advancing to step 6:
The number 48 fits into 419 8 times, leaving a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 19648.0
Deduct 384 from 419 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
The number 48 fits into 350 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 19648.7
If we subtract 336 from 350, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
If we divide 140 by 48, we get 2 and a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 19648.72
Subtract 96 from 140 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
48 goes into 440 9 times with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 19648.729
Subtract 432 from 440 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
80 divided by 48 is 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 19648.7291
The remainder is 32 after subtracting 48 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
320 divided by 48 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 19648.72916
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
When dividing 320 by 48, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 19648.729166
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 19648.729166, with a leftover of 3.2e-06.
