40279539 ÷ 848 
We want to divide 40279539 by 848.

Going ahead to step 1:
4 divided by 848 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 848

Moving on to step 2:
When dividing 40 by 848, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 848

Step 3:
The number 848 fits into 402 0 times, leaving a remainder of 402.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 402 to get 402.
Include the next digit (7) from the dividend after 402, then repeat: 4027 / 848

Going ahead to step 4:
When dividing 4027 by 848, we get 4 with a remainder of 635.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 3392 from 4027 and we're left with 635.
Append the next digit (9) from the dividend to 635 and continue with: 6359 / 848

Step 5:
The number 848 fits into 6359 7 times, leaving a remainder of 423.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we take 5936 away from 6359, we end up with 423.
Append the next digit (5) from the dividend to 423 and continue with: 4235 / 848

Moving on to step 6:
4235 divided by 848 is 4 with a remainder of 843.
Record the quotient 4 as the next digit in the result. 
Result so far: 474.0
If we subtract 3392 from 4235, we get 843.
Fetch the next digit (3) from the dividend, attach it to 843 and continue: 8433 / 848

Step 7:
848 goes into 8433 9 times with a remainder of 801.
Put 9 as the next digit of the answer. 
Result so far: 4749.0
The remainder is 801 after subtracting 7632 from 8433.
Fetch the next digit (9) from the dividend, attach it to 801 and continue: 8019 / 848

On to step 8:
848 goes into 8019 9 times with a remainder of 387.
The number 9 becomes the next digit in our result. 
Result so far: 47499.0
If we take 7632 away from 8019, we end up with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Step 9:
848 goes into 3870 4 times with a remainder of 478.
The next digit of our result is 4. 
Result so far: 47499.4
The remainder is 478 after subtracting 3392 from 3870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Advancing to step 10:
When dividing 4780 by 848, we get 5 with a remainder of 540.
The number 5 becomes the next digit in our result. 
Result so far: 47499.45
Deduct 4240 from 4780 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 11:
When dividing 5400 by 848, we get 6 with a remainder of 312.
Use 6 as the next digit of our solution. 
Result so far: 47499.456
The remainder is 312 after subtracting 5088 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 12:
If we divide 3120 by 848, we get 3 and a remainder of 576.
Record the quotient 3 as the next digit in the result. 
Result so far: 47499.4563
Subtract 2544 from 3120 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

On to step 13:
848 can be fit into 5760 6 times, resulting in a remainder of 672.
Use 6 as the next digit of our solution. 
Result so far: 47499.45636
The remainder is 672 after subtracting 5088 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Going ahead to step 14:
848 can be fit into 6720 7 times, resulting in a remainder of 784.
Use 7 as the next digit of our solution. 
Result so far: 47499.456367
If we take 5936 away from 6720, 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.

Advancing to step 15:
7840 divided by 848 is 9 with a remainder of 208.
Put 9 as the next digit of the answer. 
Result so far: 47499.4563679
Deduct 7632 from 7840 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 16:
848 can be fit into 2080 2 times, resulting in a remainder of 384.
Put 2 as the next digit of the answer. 
Result so far: 47499.45636792
If we subtract 1696 from 2080, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

After the division, we end up with 47499.45636792 and a remainder of 3.84e-07.
