654438 divided by 77 
We want to figure out the number of times 654438 can be divided by 77.

Step 1:
77 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 77

Let's proceed to step 2:
The number 77 fits into 65 0 times, leaving a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 77

Advancing to step 3:
77 goes into 654 8 times with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 616 from 654 to get 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 77

Moving on to step 4:
384 divided by 77 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we subtract 308 from 384, we get 76.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 77

Advancing to step 5:
763 divided by 77 is 9 with a remainder of 70.
The next digit of our result is 9. 
Result so far: 849.0
The remainder is 70 after subtracting 693 from 763.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 77

On to step 6:
If we divide 708 by 77, we get 9 and a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 8499.0
Subtracting 693 from 708 leaves us 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.

Step 7:
150 divided by 77 is 1 with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 8499.1
Subtracting 77 from 150 leaves us 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.

Step 8:
730 divided by 77 is 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 8499.19
If we subtract 693 from 730, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
When dividing 370 by 77, we get 4 with a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 8499.194
If we take 308 away from 370, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
If we divide 620 by 77, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 8499.1948
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.

Let's proceed to step 11:
If we divide 40 by 77, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8499.1948
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.

Advancing to step 12:
77 goes into 400 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 8499.194805
Subtracting 385 from 400 leaves us 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.

Advancing to step 13:
77 can be fit into 150 1 times, resulting in a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 8499.1948051
If we take 77 away from 150, we end up 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.

On to step 14:
The number 77 fits into 730 9 times, leaving a remainder of 37.
The next digit of our result is 9. 
Result so far: 8499.19480519
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The quotient of the division is 8499.19480519, and the remainder is 3.7e-08.
