117621 ÷ 77 
We want to divide 117621 by 77.

Let's proceed to step 1:
The number 77 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 77

Moving on to step 2:
The number 77 fits into 11 0 times, leaving a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 77

Step 3:
When dividing 117 by 77, we get 1 with a remainder of 40.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 77 from 117 leaves us with 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 77

Going ahead to step 4:
If we divide 406 by 77, we get 5 and a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 385 from 406 to get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 77

Step 5:
When dividing 212 by 77, we get 2 with a remainder of 58.
The next digit of our result is 2. 
Result so far: 152.0
If we subtract 154 from 212, we get 58.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 77

Advancing to step 6:
581 divided by 77 is 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 1527.0
The remainder is 42 after subtracting 539 from 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
420 divided by 77 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1527.5
Deduct 385 from 420 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
350 divided by 77 is 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 1527.54
Subtracting 308 from 350 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
The number 77 fits into 420 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 1527.545
Deduct 385 from 420 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
The number 77 fits into 350 4 times, leaving a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 1527.5454
Deduct 308 from 350 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
77 goes into 420 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1527.54545
Subtract 385 from 420 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 12:
77 goes into 350 4 times with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 1527.545454
Deduct 308 from 350 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
The number 77 fits into 420 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1527.5454545
If we subtract 385 from 420, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
350 divided by 77 is 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 1527.54545454
Subtracting 308 from 350 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 1527.54545454 with a balance of 4.2e-08.
