21043601 ÷ 442 
We want to divide 21043601 by 442.

Advancing to step 1:
442 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 442

Step 2:
If we divide 21 by 442, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 442

Step 3:
442 goes into 210 0 times with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 210, we end up with 210.
Append the next digit (4) from the dividend to 210 and continue with: 2104 / 442

Step 4:
442 goes into 2104 4 times with a remainder of 336.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 1768 away from 2104, we end up with 336.
Fetch the next digit (3) from the dividend, attach it to 336 and continue: 3363 / 442

Step 5:
When dividing 3363 by 442, we get 7 with a remainder of 269.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we subtract 3094 from 3363, we get 269.
Take the next digit (6) from the dividend and append it to 269, then repeat: 2696 / 442

On to step 6:
442 goes into 2696 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 476.0
Deduct 2652 from 2696 and we're left with 44.
Grab the next digit (0) from the dividend, add it to 44, then carry on: 440 / 442

Going ahead to step 7:
When dividing 440 by 442, we get 0 with a remainder of 440.
The number 0 becomes the next digit in our result. 
Result so far: 4760.0
The remainder is 440 after subtracting 0 from 440.
Include the next digit (1) from the dividend after 440, then repeat: 4401 / 442

On to step 8:
442 goes into 4401 9 times with a remainder of 423.
The next digit of our result is 9. 
Result so far: 47609.0
If we subtract 3978 from 4401, we get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Moving on to step 9:
4230 divided by 442 is 9 with a remainder of 252.
The next digit of our result is 9. 
Result so far: 47609.9
Deduct 3978 from 4230 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 10:
442 can be fit into 2520 5 times, resulting in a remainder of 310.
Use 5 as the next digit of our solution. 
Result so far: 47609.95
If we take 2210 away from 2520, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 11:
The number 442 fits into 3100 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 47609.957
The remainder is 6 after subtracting 3094 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
442 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 47609.957
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
442 goes into 600 1 times with a remainder of 158.
The next digit of our result is 1. 
Result so far: 47609.95701
Subtracting 442 from 600 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 14:
If we divide 1580 by 442, we get 3 and a remainder of 254.
Use 3 as the next digit of our solution. 
Result so far: 47609.957013
If we subtract 1326 from 1580, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 15:
If we divide 2540 by 442, we get 5 and a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 47609.9570135
Deduct 2210 from 2540 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 16:
The number 442 fits into 3300 7 times, leaving a remainder of 206.
Write down 7 as next digit of the result. 
Result so far: 47609.95701357
If we subtract 3094 from 3300, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

After the division, we end up with 47609.95701357 and a remainder of 2.06e-07.
