We're dividing 553145 by 77 
We want to divide 553145 by 77.

Step 1:
77 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 77

Step 2:
55 divided by 77 is 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Take the next digit (3) from the dividend and append it to 55, then repeat: 553 / 77

Let's proceed to step 3:
The number 77 fits into 553 7 times, leaving a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 539 away from 553, we end up with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 77

Moving on to step 4:
77 goes into 141 1 times with a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we take 77 away from 141, we end up with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 77

Let's proceed to step 5:
When dividing 644 by 77, we get 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 718.0
Subtract 616 from 644 to get 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 77

Moving on to step 6:
When dividing 285 by 77, we get 3 with a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 7183.0
If we subtract 231 from 285, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
If we divide 540 by 77, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7183.7
If we subtract 539 from 540, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
10 divided by 77 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 7183.7
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
77 can be fit into 100 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 7183.701
If we subtract 77 from 100, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 10:
77 can be fit into 230 2 times, resulting in a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 7183.7012
Deduct 154 from 230 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
The number 77 fits into 760 9 times, leaving a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 7183.70129
If we subtract 693 from 760, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 12:
If we divide 670 by 77, we get 8 and a remainder of 54.
The next digit of our result is 8. 
Result so far: 7183.701298
Deduct 616 from 670 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
The number 77 fits into 540 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7183.7012987
If we take 539 away from 540, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
When dividing 10 by 77, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7183.7012987
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 7183.7012987 and a remainder of 1e-08.
