We look at the division of 139556 by 77 
We want to figure out the number of times 139556 can be divided by 77.

Going ahead to step 1:
77 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 77

Moving on to step 2:
77 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 77

Going ahead to step 3:
77 can be fit into 139 1 times, resulting in a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 62 after subtracting 77 from 139.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 77

Let's proceed to step 4:
625 divided by 77 is 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 616 from 625 to get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 77

Moving on to step 5:
When dividing 95 by 77, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 181.0
If we take 77 away from 95, we end up with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 77

Going ahead to step 6:
The number 77 fits into 186 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 1812.0
Deduct 154 from 186 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
The number 77 fits into 320 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 1812.4
If we take 308 away from 320, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
77 can be fit into 120 1 times, resulting in a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 1812.41
If we take 77 away from 120, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
If we divide 430 by 77, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 1812.415
Subtracting 385 from 430 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
The number 77 fits into 450 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 1812.4155
Subtracting 385 from 450 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 1812.4155 with a remaining 0.00065.
