99801950 ÷ 125 
Our goal is to divide 99801950 by 125.

Step 1:
The number 125 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 125

On to step 2:
99 divided by 125 is 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 125

Moving on to step 3:
125 can be fit into 998 7 times, resulting in a remainder of 123.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 875 away from 998, we end up with 123.
Grab the next digit (0) from the dividend, add it to 123, then carry on: 1230 / 125

Moving on to step 4:
125 goes into 1230 9 times with a remainder of 105.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtracting 1125 from 1230 leaves us with 105.
Append the next digit (1) from the dividend to 105 and continue with: 1051 / 125

Going ahead to step 5:
The number 125 fits into 1051 8 times, leaving a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 798.0
Subtract 1000 from 1051 to get 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 125

Going ahead to step 6:
If we divide 519 by 125, we get 4 and a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 7984.0
Subtracting 500 from 519 leaves us with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 125

Moving on to step 7:
The number 125 fits into 195 1 times, leaving a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 79841.0
Subtracting 125 from 195 leaves us with 70.
Bring next digit (0) of the dividend behind the 70 and repeat the process: 700 / 125

Let's proceed to step 8:
The number 125 fits into 700 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 798415.0
If we take 625 away from 700, 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.

Going ahead to step 9:
If we divide 750 by 125, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 798415.6
The remainder is 0 after subtracting 750 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 125 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 798415.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
0 divided by 125 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 798415.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 798415.6 and a remainder of 0.0.
