Let's divide 140170 by 77
Our goal is to divide 140170 by 77.

On to step 1:
1 divided by 77 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 77

Going ahead to step 2:
77 can be fit into 14 0 times, resulting in a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 77

Moving on to step 3:
The number 77 fits into 140 1 times, leaving a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 77 from 140 and we're left with 63.
Include the next digit (1) from the dividend after 63, then repeat: 631 / 77

Advancing to step 4:
631 divided by 77 is 8 with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 616 from 631, we get 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 77

Step 5:
157 divided by 77 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
Subtracting 154 from 157 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 77

Let's proceed to step 6:
The number 77 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1820.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
77 goes into 300 3 times with a remainder of 69.
The next digit of our result is 3. 
Result so far: 1820.3
Subtract 231 from 300 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 8:
690 divided by 77 is 8 with a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 1820.38
Deduct 616 from 690 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
If we divide 740 by 77, we get 9 and a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 1820.389
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 10:
When dividing 470 by 77, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1820.3896
If we subtract 462 from 470, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
77 goes into 80 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1820.38961
Subtract 77 from 80 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
If we divide 30 by 77, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 1820.38961
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
The number 77 fits into 300 3 times, leaving a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 1820.3896103
Deduct 231 from 300 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 14:
The number 77 fits into 690 8 times, leaving a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 1820.38961038
The remainder is 74 after subtracting 616 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 1820.38961038 and a remainder of 7.4e-08.
