107939 ÷ 77 
We want to divide 107939 by 77.

Step 1:
When dividing 1 by 77, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 77

Advancing to step 2:
The number 77 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 77

Going ahead to step 3:
107 divided by 77 is 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 77 from 107 to get 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 77

Advancing to step 4:
If we divide 309 by 77, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 308 from 309 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 77

Step 5:
77 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 140.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 77

Step 6:
139 divided by 77 is 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 1401.0
The remainder is 62 after subtracting 77 from 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 7:
77 goes into 620 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1401.8
Deduct 616 from 620 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
If we divide 40 by 77, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1401.8
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
77 goes into 400 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1401.805
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
If we divide 150 by 77, we get 1 and a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 1401.8051
Deduct 77 from 150 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 11:
If we divide 730 by 77, we get 9 and a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 1401.80519
If we take 693 away from 730, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
If we divide 370 by 77, we get 4 and a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 1401.805194
Subtract 308 from 370 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 13:
77 goes into 620 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 1401.8051948
Subtracting 616 from 620 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
The number 77 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1401.8051948
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 1401.8051948 with a remaining 4e-08.
