83985401 ÷ 778 
We want to divide 83985401 by 778.

Advancing to step 1:
If we divide 8 by 778, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 778

Advancing to step 2:
When dividing 83 by 778, we get 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 778

Let's proceed to step 3:
When dividing 839 by 778, we get 1 with a remainder of 61.
The next digit of our result is 1. 
Result so far: 1.0
If we take 778 away from 839, we end up with 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 778

On to step 4:
When dividing 618 by 778, we get 0 with a remainder of 618.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 618 after subtracting 0 from 618.
Append the next digit (5) from the dividend to 618 and continue with: 6185 / 778

Going ahead to step 5:
The number 778 fits into 6185 7 times, leaving a remainder of 739.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we subtract 5446 from 6185, we get 739.
Include the next digit (4) from the dividend after 739, then repeat: 7394 / 778

On to step 6:
The number 778 fits into 7394 9 times, leaving a remainder of 392.
Use 9 as the next digit of our solution. 
Result so far: 1079.0
If we take 7002 away from 7394, we end up with 392.
Bring next digit (0) of the dividend behind the 392 and repeat the process: 3920 / 778

Advancing to step 7:
778 can be fit into 3920 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 10795.0
Subtract 3890 from 3920 to get 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 778

Step 8:
When dividing 301 by 778, we get 0 with a remainder of 301.
Write down 0 as next digit of the result. 
Result so far: 107950.0
Deduct 0 from 301 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 9:
778 can be fit into 3010 3 times, resulting in a remainder of 676.
Put 3 as the next digit of the answer. 
Result so far: 107950.3
Subtract 2334 from 3010 to get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Advancing to step 10:
When dividing 6760 by 778, we get 8 with a remainder of 536.
The next digit of our result is 8. 
Result so far: 107950.38
Subtract 6224 from 6760 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

On to step 11:
When dividing 5360 by 778, we get 6 with a remainder of 692.
Use 6 as the next digit of our solution. 
Result so far: 107950.386
If we subtract 4668 from 5360, we get 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Let's proceed to step 12:
778 goes into 6920 8 times with a remainder of 696.
The next digit of our result is 8. 
Result so far: 107950.3868
Subtracting 6224 from 6920 leaves us with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

On to step 13:
778 goes into 6960 8 times with a remainder of 736.
Record the quotient 8 as the next digit in the result. 
Result so far: 107950.38688
If we take 6224 away from 6960, we end up with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

The quotient of the division is 107950.38688, and the remainder is 0.000736.
