We look at the division of 78143370 by 777 
We're looking to find how many times 777 goes into 78143370.

Let's proceed to step 1:
When dividing 7 by 777, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 777

Advancing to step 2:
78 divided by 777 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 777

Let's proceed to step 3:
777 goes into 781 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 777 from 781, we get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 777

Moving on to step 4:
44 divided by 777 is 0 with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 44 to get 44.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 777

Moving on to step 5:
If we divide 443 by 777, we get 0 and a remainder of 443.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 443 and we're left with 443.
Take the next digit (3) from the dividend and append it to 443, then repeat: 4433 / 777

Moving on to step 6:
4433 divided by 777 is 5 with a remainder of 548.
Put 5 as the next digit of the answer. 
Result so far: 1005.0
If we subtract 3885 from 4433, we get 548.
Grab the next digit (7) from the dividend, add it to 548, then carry on: 5487 / 777

Step 7:
5487 divided by 777 is 7 with a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 10057.0
Subtract 5439 from 5487 to get 48.
Grab the next digit (0) from the dividend, add it to 48, then carry on: 480 / 777

On to step 8:
The number 777 fits into 480 0 times, leaving a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 100570.0
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 9:
4800 divided by 777 is 6 with a remainder of 138.
The number 6 becomes the next digit in our result. 
Result so far: 100570.6
If we take 4662 away from 4800, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 10:
If we divide 1380 by 777, we get 1 and a remainder of 603.
The next digit of our result is 1. 
Result so far: 100570.61
If we take 777 away from 1380, we end up with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Going ahead to step 11:
6030 divided by 777 is 7 with a remainder of 591.
Use 7 as the next digit of our solution. 
Result so far: 100570.617
Subtract 5439 from 6030 to get 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Advancing to step 12:
When dividing 5910 by 777, we get 7 with a remainder of 471.
Record the quotient 7 as the next digit in the result. 
Result so far: 100570.6177
Subtract 5439 from 5910 to get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

The quotient of the division is 100570.6177, and the remainder is 0.00471.
