We look at the division of 21990376 by 337 
We want to figure out the number of times 21990376 can be divided by 337.

Moving on to step 1:
The number 337 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 337

Moving on to step 2:
337 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 337

Moving on to step 3:
When dividing 219 by 337, we get 0 with a remainder of 219.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 219 leaves us with 219.
Fetch the next digit (9) from the dividend, attach it to 219 and continue: 2199 / 337

Going ahead to step 4:
If we divide 2199 by 337, we get 6 and a remainder of 177.
The next digit of our result is 6. 
Result so far: 6.0
If we take 2022 away from 2199, we end up with 177.
Bring next digit (0) of the dividend behind the 177 and repeat the process: 1770 / 337

Step 5:
The number 337 fits into 1770 5 times, leaving a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtracting 1685 from 1770 leaves us with 85.
Include the next digit (3) from the dividend after 85, then repeat: 853 / 337

Advancing to step 6:
853 divided by 337 is 2 with a remainder of 179.
Write down 2 as next digit of the result. 
Result so far: 652.0
Deduct 674 from 853 and we're left with 179.
Include the next digit (7) from the dividend after 179, then repeat: 1797 / 337

Moving on to step 7:
If we divide 1797 by 337, we get 5 and a remainder of 112.
The next digit of our result is 5. 
Result so far: 6525.0
Deduct 1685 from 1797 and we're left with 112.
Grab the next digit (6) from the dividend, add it to 112, then carry on: 1126 / 337

Step 8:
1126 divided by 337 is 3 with a remainder of 115.
Write down 3 as next digit of the result. 
Result so far: 65253.0
Subtract 1011 from 1126 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 9:
If we divide 1150 by 337, we get 3 and a remainder of 139.
Write down 3 as next digit of the result. 
Result so far: 65253.3
The remainder is 139 after subtracting 1011 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 10:
337 goes into 1390 4 times with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 65253.34
Deduct 1348 from 1390 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
337 can be fit into 420 1 times, resulting in a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 65253.341
Subtract 337 from 420 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 12:
337 can be fit into 830 2 times, resulting in a remainder of 156.
The number 2 becomes the next digit in our result. 
Result so far: 65253.3412
If we subtract 674 from 830, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 13:
If we divide 1560 by 337, we get 4 and a remainder of 212.
Use 4 as the next digit of our solution. 
Result so far: 65253.34124
If we subtract 1348 from 1560, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 14:
337 can be fit into 2120 6 times, resulting in a remainder of 98.
Write down 6 as next digit of the result. 
Result so far: 65253.341246
Deduct 2022 from 2120 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 15:
337 can be fit into 980 2 times, resulting in a remainder of 306.
Put 2 as the next digit of the answer. 
Result so far: 65253.3412462
Subtract 674 from 980 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 16:
When dividing 3060 by 337, we get 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 65253.34124629
Subtract 3033 from 3060 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 65253.34124629 with a remaining 2.7e-08.
