Let's divide 77405881 by 442
We want to divide 77405881 by 442.

On to step 1:
If we divide 7 by 442, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 442

Going ahead to step 2:
If we divide 77 by 442, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 442

On to step 3:
If we divide 774 by 442, we get 1 and a remainder of 332.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 442 from 774, we get 332.
Include the next digit (0) from the dividend after 332, then repeat: 3320 / 442

On to step 4:
442 can be fit into 3320 7 times, resulting in a remainder of 226.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 3094 from 3320 and we're left with 226.
Take the next digit (5) from the dividend and append it to 226, then repeat: 2265 / 442

On to step 5:
442 goes into 2265 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 175.0
Deduct 2210 from 2265 and we're left with 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 442

Advancing to step 6:
The number 442 fits into 558 1 times, leaving a remainder of 116.
Put 1 as the next digit of the answer. 
Result so far: 1751.0
Subtracting 442 from 558 leaves us with 116.
Grab the next digit (8) from the dividend, add it to 116, then carry on: 1168 / 442

Moving on to step 7:
The number 442 fits into 1168 2 times, leaving a remainder of 284.
Put 2 as the next digit of the answer. 
Result so far: 17512.0
If we subtract 884 from 1168, we get 284.
Grab the next digit (1) from the dividend, add it to 284, then carry on: 2841 / 442

Going ahead to step 8:
442 goes into 2841 6 times with a remainder of 189.
Write down 6 as next digit of the result. 
Result so far: 175126.0
Subtracting 2652 from 2841 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 9:
When dividing 1890 by 442, we get 4 with a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 175126.4
If we take 1768 away from 1890, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 10:
When dividing 1220 by 442, we get 2 with a remainder of 336.
The number 2 becomes the next digit in our result. 
Result so far: 175126.42
If we subtract 884 from 1220, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 11:
442 can be fit into 3360 7 times, resulting in a remainder of 266.
Put 7 as the next digit of the answer. 
Result so far: 175126.427
If we subtract 3094 from 3360, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 12:
If we divide 2660 by 442, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 175126.4276
Subtract 2652 from 2660 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.

Step 13:
If we divide 80 by 442, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 175126.4276
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
442 can be fit into 800 1 times, resulting in a remainder of 358.
Put 1 as the next digit of the answer. 
Result so far: 175126.427601
The remainder is 358 after subtracting 442 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 15:
442 can be fit into 3580 8 times, resulting in a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 175126.4276018
If we take 3536 away from 3580, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 16:
The number 442 fits into 440 0 times, leaving a remainder of 440.
Record the quotient 0 as the next digit in the result. 
Result so far: 175126.4276018
If we subtract 0 from 440, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

After the division, we end up with 175126.4276018 and a remainder of 4.4e-07.
