We're dividing 77099950 by 181 
We want to figure out the number of times 77099950 can be divided by 181.

Moving on to step 1:
If we divide 7 by 181, 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.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 181

Let's proceed to step 2:
The number 181 fits into 77 0 times, leaving a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 181

On to step 3:
The number 181 fits into 770 4 times, leaving a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 724 from 770, we get 46.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 181

Moving on to step 4:
181 can be fit into 469 2 times, resulting in a remainder of 107.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 107 after subtracting 362 from 469.
Include the next digit (9) from the dividend after 107, then repeat: 1079 / 181

Moving on to step 5:
181 can be fit into 1079 5 times, resulting in a remainder of 174.
Use 5 as the next digit of our solution. 
Result so far: 425.0
The remainder is 174 after subtracting 905 from 1079.
Include the next digit (9) from the dividend after 174, then repeat: 1749 / 181

Moving on to step 6:
If we divide 1749 by 181, we get 9 and a remainder of 120.
Record the quotient 9 as the next digit in the result. 
Result so far: 4259.0
If we subtract 1629 from 1749, we get 120.
Include the next digit (5) from the dividend after 120, then repeat: 1205 / 181

On to step 7:
If we divide 1205 by 181, we get 6 and a remainder of 119.
The number 6 becomes the next digit in our result. 
Result so far: 42596.0
Deduct 1086 from 1205 and we're left with 119.
Append the next digit (0) from the dividend to 119 and continue with: 1190 / 181

Going ahead to step 8:
When dividing 1190 by 181, we get 6 with a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 425966.0
If we subtract 1086 from 1190, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 9:
181 goes into 1040 5 times with a remainder of 135.
The next digit of our result is 5. 
Result so far: 425966.5
Subtracting 905 from 1040 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 10:
When dividing 1350 by 181, we get 7 with a remainder of 83.
The number 7 becomes the next digit in our result. 
Result so far: 425966.57
Subtract 1267 from 1350 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 11:
181 goes into 830 4 times with a remainder of 106.
Write down 4 as next digit of the result. 
Result so far: 425966.574
If we take 724 away from 830, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 12:
The number 181 fits into 1060 5 times, leaving a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 425966.5745
The remainder is 155 after subtracting 905 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 13:
181 goes into 1550 8 times with a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 425966.57458
Deduct 1448 from 1550 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 14:
181 goes into 1020 5 times with a remainder of 115.
The next digit of our result is 5. 
Result so far: 425966.574585
If we take 905 away from 1020, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 15:
The number 181 fits into 1150 6 times, leaving a remainder of 64.
The next digit of our result is 6. 
Result so far: 425966.5745856
Subtract 1086 from 1150 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 16:
The number 181 fits into 640 3 times, leaving a remainder of 97.
The next digit of our result is 3. 
Result so far: 425966.57458563
Deduct 543 from 640 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

After the division, we end up with 425966.57458563 and a remainder of 9.7e-08.
