99722622 ÷ 399 
We're looking to find how many times 399 goes into 99722622.

Advancing to step 1:
When dividing 9 by 399, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 399

Step 2:
If we divide 99 by 399, we get 0 and a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Append the next digit (7) from the dividend to 99 and continue with: 997 / 399

Advancing to step 3:
When dividing 997 by 399, we get 2 with a remainder of 199.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 199 after subtracting 798 from 997.
Bring next digit (2) of the dividend behind the 199 and repeat the process: 1992 / 399

Advancing to step 4:
The number 399 fits into 1992 4 times, leaving a remainder of 396.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 396 after subtracting 1596 from 1992.
Take the next digit (2) from the dividend and append it to 396, then repeat: 3962 / 399

Let's proceed to step 5:
399 can be fit into 3962 9 times, resulting in a remainder of 371.
Use 9 as the next digit of our solution. 
Result so far: 249.0
Subtracting 3591 from 3962 leaves us with 371.
Append the next digit (6) from the dividend to 371 and continue with: 3716 / 399

Moving on to step 6:
399 goes into 3716 9 times with a remainder of 125.
Write down 9 as next digit of the result. 
Result so far: 2499.0
Deduct 3591 from 3716 and we're left with 125.
Include the next digit (2) from the dividend after 125, then repeat: 1252 / 399

On to step 7:
The number 399 fits into 1252 3 times, leaving a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 24993.0
Subtracting 1197 from 1252 leaves us with 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 399

Step 8:
If we divide 552 by 399, we get 1 and a remainder of 153.
The next digit of our result is 1. 
Result so far: 249931.0
Subtract 399 from 552 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 9:
399 goes into 1530 3 times with a remainder of 333.
The next digit of our result is 3. 
Result so far: 249931.3
Deduct 1197 from 1530 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Step 10:
The number 399 fits into 3330 8 times, leaving a remainder of 138.
Record the quotient 8 as the next digit in the result. 
Result so far: 249931.38
Subtract 3192 from 3330 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 11:
1380 divided by 399 is 3 with a remainder of 183.
Use 3 as the next digit of our solution. 
Result so far: 249931.383
If we subtract 1197 from 1380, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 12:
399 goes into 1830 4 times with a remainder of 234.
The number 4 becomes the next digit in our result. 
Result so far: 249931.3834
The remainder is 234 after subtracting 1596 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 13:
The number 399 fits into 2340 5 times, leaving a remainder of 345.
Record the quotient 5 as the next digit in the result. 
Result so far: 249931.38345
Deduct 1995 from 2340 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 14:
3450 divided by 399 is 8 with a remainder of 258.
Write down 8 as next digit of the result. 
Result so far: 249931.383458
If we take 3192 away from 3450, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 15:
When dividing 2580 by 399, we get 6 with a remainder of 186.
Record the quotient 6 as the next digit in the result. 
Result so far: 249931.3834586
If we subtract 2394 from 2580, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 16:
When dividing 1860 by 399, we get 4 with a remainder of 264.
The number 4 becomes the next digit in our result. 
Result so far: 249931.38345864
Subtracting 1596 from 1860 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

The final outcome is 249931.38345864, with a leftover of 2.64e-07.
