We divide 72220186 by 523
We want to figure out the number of times 72220186 can be divided by 523.

Going ahead to step 1:
If we divide 7 by 523, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 523

Let's proceed to step 2:
523 can be fit into 72 0 times, resulting in a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Take the next digit (2) from the dividend and append it to 72, then repeat: 722 / 523

Let's proceed to step 3:
The number 523 fits into 722 1 times, leaving a remainder of 199.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 523 away from 722, we end up with 199.
Include the next digit (2) from the dividend after 199, then repeat: 1992 / 523

Step 4:
523 can be fit into 1992 3 times, resulting in a remainder of 423.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1569 from 1992 leaves us with 423.
Fetch the next digit (0) from the dividend, attach it to 423 and continue: 4230 / 523

Advancing to step 5:
The number 523 fits into 4230 8 times, leaving a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
Deduct 4184 from 4230 and we're left with 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 523

Moving on to step 6:
If we divide 461 by 523, we get 0 and a remainder of 461.
Write down 0 as next digit of the result. 
Result so far: 1380.0
Deduct 0 from 461 and we're left with 461.
Take the next digit (8) from the dividend and append it to 461, then repeat: 4618 / 523

Moving on to step 7:
523 goes into 4618 8 times with a remainder of 434.
The number 8 becomes the next digit in our result. 
Result so far: 13808.0
The remainder is 434 after subtracting 4184 from 4618.
Fetch the next digit (6) from the dividend, attach it to 434 and continue: 4346 / 523

Moving on to step 8:
523 goes into 4346 8 times with a remainder of 162.
Use 8 as the next digit of our solution. 
Result so far: 138088.0
If we take 4184 away from 4346, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 9:
The number 523 fits into 1620 3 times, leaving a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 138088.3
Subtracting 1569 from 1620 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 10:
If we divide 510 by 523, we get 0 and a remainder of 510.
Write down 0 as next digit of the result. 
Result so far: 138088.3
Deduct 0 from 510 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 11:
When dividing 5100 by 523, we get 9 with a remainder of 393.
Use 9 as the next digit of our solution. 
Result so far: 138088.309
Subtracting 4707 from 5100 leaves us with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Step 12:
523 can be fit into 3930 7 times, resulting in a remainder of 269.
Put 7 as the next digit of the answer. 
Result so far: 138088.3097
If we subtract 3661 from 3930, we get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 13:
The number 523 fits into 2690 5 times, leaving a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 138088.30975
If we take 2615 away from 2690, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 14:
523 can be fit into 750 1 times, resulting in a remainder of 227.
The number 1 becomes the next digit in our result. 
Result so far: 138088.309751
If we subtract 523 from 750, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Advancing to step 15:
523 goes into 2270 4 times with a remainder of 178.
The next digit of our result is 4. 
Result so far: 138088.3097514
Subtracting 2092 from 2270 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 16:
When dividing 1780 by 523, we get 3 with a remainder of 211.
Use 3 as the next digit of our solution. 
Result so far: 138088.30975143
If we subtract 1569 from 1780, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

After the division, we end up with 138088.30975143 and a remainder of 2.11e-07.
