We look at the division of 9721993 by 446 
Let's see how many times 446 fits into 9721993.

On to step 1:
If we divide 9 by 446, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 446

On to step 2:
If we divide 97 by 446, we get 0 and a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Include the next digit (2) from the dividend after 97, then repeat: 972 / 446

On to step 3:
446 can be fit into 972 2 times, resulting in a remainder of 80.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 892 from 972 leaves us with 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 446

Advancing to step 4:
446 can be fit into 801 1 times, resulting in a remainder of 355.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 446 from 801 to get 355.
Grab the next digit (9) from the dividend, add it to 355, then carry on: 3559 / 446

Going ahead to step 5:
If we divide 3559 by 446, we get 7 and a remainder of 437.
Write down 7 as next digit of the result. 
Result so far: 217.0
The remainder is 437 after subtracting 3122 from 3559.
Grab the next digit (9) from the dividend, add it to 437, then carry on: 4379 / 446

Step 6:
446 can be fit into 4379 9 times, resulting in a remainder of 365.
Record the quotient 9 as the next digit in the result. 
Result so far: 2179.0
Deduct 4014 from 4379 and we're left with 365.
Include the next digit (3) from the dividend after 365, then repeat: 3653 / 446

Going ahead to step 7:
446 can be fit into 3653 8 times, resulting in a remainder of 85.
The number 8 becomes the next digit in our result. 
Result so far: 21798.0
Subtracting 3568 from 3653 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 8:
When dividing 850 by 446, we get 1 with a remainder of 404.
Use 1 as the next digit of our solution. 
Result so far: 21798.1
Deduct 446 from 850 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 9:
4040 divided by 446 is 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 21798.19
The remainder is 26 after subtracting 4014 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
260 divided by 446 is 0 with a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 21798.19
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 11:
446 can be fit into 2600 5 times, resulting in a remainder of 370.
Record the quotient 5 as the next digit in the result. 
Result so far: 21798.1905
If we subtract 2230 from 2600, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 12:
The number 446 fits into 3700 8 times, leaving a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 21798.19058
Subtracting 3568 from 3700 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 13:
1320 divided by 446 is 2 with a remainder of 428.
Use 2 as the next digit of our solution. 
Result so far: 21798.190582
Subtracting 892 from 1320 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 14:
When dividing 4280 by 446, we get 9 with a remainder of 266.
Write down 9 as next digit of the result. 
Result so far: 21798.1905829
The remainder is 266 after subtracting 4014 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 15:
446 goes into 2660 5 times with a remainder of 430.
Put 5 as the next digit of the answer. 
Result so far: 21798.19058295
Subtract 2230 from 2660 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Our division results in 21798.19058295 with a remaining 4.3e-07.
