99641981 ÷ 165 
We want to figure out the number of times 99641981 can be divided by 165.

Going ahead to step 1:
The number 165 fits into 9 0 times, leaving 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 / 165

On to step 2:
99 divided by 165 is 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Include the next digit (6) from the dividend after 99, then repeat: 996 / 165

On to step 3:
165 can be fit into 996 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 990 from 996, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 165

Step 4:
The number 165 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Subtract 0 from 64 to get 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 165

Going ahead to step 5:
The number 165 fits into 641 3 times, leaving a remainder of 146.
Use 3 as the next digit of our solution. 
Result so far: 603.0
Subtract 495 from 641 to get 146.
Take the next digit (9) from the dividend and append it to 146, then repeat: 1469 / 165

Going ahead to step 6:
If we divide 1469 by 165, we get 8 and a remainder of 149.
Use 8 as the next digit of our solution. 
Result so far: 6038.0
If we take 1320 away from 1469, we end up with 149.
Take the next digit (8) from the dividend and append it to 149, then repeat: 1498 / 165

Let's proceed to step 7:
165 goes into 1498 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 60389.0
Subtracting 1485 from 1498 leaves us with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 165

On to step 8:
If we divide 131 by 165, we get 0 and a remainder of 131.
Use 0 as the next digit of our solution. 
Result so far: 603890.0
Subtract 0 from 131 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 9:
1310 divided by 165 is 7 with a remainder of 155.
Write down 7 as next digit of the result. 
Result so far: 603890.7
If we subtract 1155 from 1310, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 10:
The number 165 fits into 1550 9 times, leaving a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 603890.79
If we take 1485 away from 1550, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 11:
165 can be fit into 650 3 times, resulting in a remainder of 155.
Record the quotient 3 as the next digit in the result. 
Result so far: 603890.793
If we subtract 495 from 650, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 12:
If we divide 1550 by 165, we get 9 and a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 603890.7939
Subtracting 1485 from 1550 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 13:
The number 165 fits into 650 3 times, leaving a remainder of 155.
Put 3 as the next digit of the answer. 
Result so far: 603890.79393
The remainder is 155 after subtracting 495 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 14:
When dividing 1550 by 165, we get 9 with a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 603890.793939
Deduct 1485 from 1550 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 15:
When dividing 650 by 165, we get 3 with a remainder of 155.
Use 3 as the next digit of our solution. 
Result so far: 603890.7939393
If we take 495 away from 650, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 16:
1550 divided by 165 is 9 with a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 603890.79393939
If we take 1485 away from 1550, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 603890.79393939, and the remainder is 6.5e-08.
