Let's divide 21689338 by 445
We're looking to find how many times 445 goes into 21689338.

Moving on to step 1:
If we divide 2 by 445, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 445

Moving on to step 2:
The number 445 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 445

Advancing to step 3:
When dividing 216 by 445, we get 0 with a remainder of 216.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 216 leaves us with 216.
Append the next digit (8) from the dividend to 216 and continue with: 2168 / 445

Step 4:
When dividing 2168 by 445, we get 4 with a remainder of 388.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 1780 from 2168 to get 388.
Bring next digit (9) of the dividend behind the 388 and repeat the process: 3889 / 445

Step 5:
If we divide 3889 by 445, we get 8 and a remainder of 329.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtracting 3560 from 3889 leaves us with 329.
Fetch the next digit (3) from the dividend, attach it to 329 and continue: 3293 / 445

Moving on to step 6:
If we divide 3293 by 445, we get 7 and a remainder of 178.
The next digit of our result is 7. 
Result so far: 487.0
If we take 3115 away from 3293, we end up with 178.
Grab the next digit (3) from the dividend, add it to 178, then carry on: 1783 / 445

On to step 7:
If we divide 1783 by 445, we get 4 and a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4874.0
Deduct 1780 from 1783 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 445

Advancing to step 8:
If we divide 38 by 445, we get 0 and a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 48740.0
Deduct 0 from 38 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
The number 445 fits into 380 0 times, leaving a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 48740.0
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 10:
When dividing 3800 by 445, we get 8 with a remainder of 240.
The next digit of our result is 8. 
Result so far: 48740.08
If we take 3560 away from 3800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
445 goes into 2400 5 times with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 48740.085
The remainder is 175 after subtracting 2225 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 12:
The number 445 fits into 1750 3 times, leaving a remainder of 415.
The number 3 becomes the next digit in our result. 
Result so far: 48740.0853
If we subtract 1335 from 1750, we get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Going ahead to step 13:
445 goes into 4150 9 times with a remainder of 145.
The next digit of our result is 9. 
Result so far: 48740.08539
The remainder is 145 after subtracting 4005 from 4150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 14:
1450 divided by 445 is 3 with a remainder of 115.
Put 3 as the next digit of the answer. 
Result so far: 48740.085393
If we take 1335 away from 1450, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 15:
1150 divided by 445 is 2 with a remainder of 260.
Put 2 as the next digit of the answer. 
Result so far: 48740.0853932
If we take 890 away from 1150, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 16:
If we divide 2600 by 445, we get 5 and a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 48740.08539325
Deduct 2225 from 2600 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

After the division, we end up with 48740.08539325 and a remainder of 3.75e-07.
