139170 divided by 77 
Let's see how many times 77 fits into 139170.

On to step 1:
77 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 77

On to step 2:
If we divide 13 by 77, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 77

On to step 3:
139 divided by 77 is 1 with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 77 from 139 leaves us with 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 77

Moving on to step 4:
If we divide 621 by 77, we get 8 and a remainder of 5.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 5 after subtracting 616 from 621.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 77

On to step 5:
77 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
Deduct 0 from 57 and we're left with 57.
Bring next digit (0) of the dividend behind the 57 and repeat the process: 570 / 77

Going ahead to step 6:
When dividing 570 by 77, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 1807.0
Subtracting 539 from 570 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
310 divided by 77 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 1807.4
Subtract 308 from 310 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
If we divide 20 by 77, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1807.4
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 77 fits into 200 2 times, leaving a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 1807.402
Subtracting 154 from 200 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
When dividing 460 by 77, we get 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 1807.4025
Deduct 385 from 460 and we're left 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.

Moving on to step 11:
When dividing 750 by 77, we get 9 with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 1807.40259
Deduct 693 from 750 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 12:
77 goes into 570 7 times with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 1807.402597
The remainder is 31 after subtracting 539 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
The number 77 fits into 310 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 1807.4025974
Subtract 308 from 310 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
If we divide 20 by 77, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1807.4025974
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 1807.4025974, and the remainder is 2e-08.
