22201639 ÷ 397 
We're looking to find how many times 397 goes into 22201639.

Moving on to step 1:
397 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 397

Advancing to step 2:
If we divide 22 by 397, we get 0 and a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 397

Advancing to step 3:
When dividing 222 by 397, we get 0 with a remainder of 222.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 222 to get 222.
Bring next digit (0) of the dividend behind the 222 and repeat the process: 2220 / 397

On to step 4:
If we divide 2220 by 397, we get 5 and a remainder of 235.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 1985 from 2220 leaves us with 235.
Bring next digit (1) of the dividend behind the 235 and repeat the process: 2351 / 397

Advancing to step 5:
When dividing 2351 by 397, we get 5 with a remainder of 366.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Deduct 1985 from 2351 and we're left with 366.
Bring next digit (6) of the dividend behind the 366 and repeat the process: 3666 / 397

Let's proceed to step 6:
The number 397 fits into 3666 9 times, leaving a remainder of 93.
The number 9 becomes the next digit in our result. 
Result so far: 559.0
Deduct 3573 from 3666 and we're left with 93.
Append the next digit (3) from the dividend to 93 and continue with: 933 / 397

Advancing to step 7:
The number 397 fits into 933 2 times, leaving a remainder of 139.
The number 2 becomes the next digit in our result. 
Result so far: 5592.0
Subtract 794 from 933 to get 139.
Fetch the next digit (9) from the dividend, attach it to 139 and continue: 1399 / 397

Step 8:
If we divide 1399 by 397, we get 3 and a remainder of 208.
Write down 3 as next digit of the result. 
Result so far: 55923.0
If we take 1191 away from 1399, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 9:
2080 divided by 397 is 5 with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 55923.5
The remainder is 95 after subtracting 1985 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 10:
397 can be fit into 950 2 times, resulting in a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 55923.52
Subtracting 794 from 950 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 11:
1560 divided by 397 is 3 with a remainder of 369.
Write down 3 as next digit of the result. 
Result so far: 55923.523
The remainder is 369 after subtracting 1191 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 12:
397 can be fit into 3690 9 times, resulting in a remainder of 117.
Write down 9 as next digit of the result. 
Result so far: 55923.5239
If we take 3573 away from 3690, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 13:
If we divide 1170 by 397, we get 2 and a remainder of 376.
Put 2 as the next digit of the answer. 
Result so far: 55923.52392
The remainder is 376 after subtracting 794 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 14:
397 can be fit into 3760 9 times, resulting in a remainder of 187.
Write down 9 as next digit of the result. 
Result so far: 55923.523929
If we subtract 3573 from 3760, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 15:
The number 397 fits into 1870 4 times, leaving a remainder of 282.
Record the quotient 4 as the next digit in the result. 
Result so far: 55923.5239294
The remainder is 282 after subtracting 1588 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 16:
2820 divided by 397 is 7 with a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 55923.52392947
If we subtract 2779 from 2820, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The quotient of the division is 55923.52392947, and the remainder is 4.1e-08.
