84158166 divided by 778 
Let's see how many times 778 fits into 84158166.

Let's proceed to step 1:
The number 778 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 778

Advancing to step 2:
When dividing 84 by 778, we get 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Take the next digit (1) from the dividend and append it to 84, then repeat: 841 / 778

Moving on to step 3:
If we divide 841 by 778, we get 1 and a remainder of 63.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 778 from 841 leaves us with 63.
Append the next digit (5) from the dividend to 63 and continue with: 635 / 778

Let's proceed to step 4:
If we divide 635 by 778, we get 0 and a remainder of 635.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 635 and we're left with 635.
Fetch the next digit (8) from the dividend, attach it to 635 and continue: 6358 / 778

Step 5:
6358 divided by 778 is 8 with a remainder of 134.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
If we subtract 6224 from 6358, we get 134.
Bring next digit (1) of the dividend behind the 134 and repeat the process: 1341 / 778

Let's proceed to step 6:
When dividing 1341 by 778, we get 1 with a remainder of 563.
Record the quotient 1 as the next digit in the result. 
Result so far: 1081.0
Subtract 778 from 1341 to get 563.
Grab the next digit (6) from the dividend, add it to 563, then carry on: 5636 / 778

Let's proceed to step 7:
When dividing 5636 by 778, we get 7 with a remainder of 190.
Put 7 as the next digit of the answer. 
Result so far: 10817.0
Deduct 5446 from 5636 and we're left with 190.
Bring next digit (6) of the dividend behind the 190 and repeat the process: 1906 / 778

Advancing to step 8:
If we divide 1906 by 778, we get 2 and a remainder of 350.
Write down 2 as next digit of the result. 
Result so far: 108172.0
The remainder is 350 after subtracting 1556 from 1906.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 9:
When dividing 3500 by 778, we get 4 with a remainder of 388.
Record the quotient 4 as the next digit in the result. 
Result so far: 108172.4
If we take 3112 away from 3500, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 10:
778 can be fit into 3880 4 times, resulting in a remainder of 768.
Write down 4 as next digit of the result. 
Result so far: 108172.44
Deduct 3112 from 3880 and we're left with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

After the division, we end up with 108172.44 and a remainder of 0.768.
