61908431 divided by 778 
We want to figure out the number of times 61908431 can be divided by 778.

Step 1:
If we divide 6 by 778, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 778

Going ahead to step 2:
When dividing 61 by 778, we get 0 with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 778

Advancing to step 3:
778 goes into 619 0 times with a remainder of 619.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 619 and we're left with 619.
Include the next digit (0) from the dividend after 619, then repeat: 6190 / 778

On to step 4:
778 goes into 6190 7 times with a remainder of 744.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 5446 away from 6190, we end up with 744.
Grab the next digit (8) from the dividend, add it to 744, then carry on: 7448 / 778

Advancing to step 5:
If we divide 7448 by 778, we get 9 and a remainder of 446.
The next digit of our result is 9. 
Result so far: 79.0
Subtract 7002 from 7448 to get 446.
Include the next digit (4) from the dividend after 446, then repeat: 4464 / 778

Advancing to step 6:
4464 divided by 778 is 5 with a remainder of 574.
Record the quotient 5 as the next digit in the result. 
Result so far: 795.0
If we take 3890 away from 4464, we end up with 574.
Bring next digit (3) of the dividend behind the 574 and repeat the process: 5743 / 778

Advancing to step 7:
The number 778 fits into 5743 7 times, leaving a remainder of 297.
The number 7 becomes the next digit in our result. 
Result so far: 7957.0
Subtract 5446 from 5743 to get 297.
Include the next digit (1) from the dividend after 297, then repeat: 2971 / 778

On to step 8:
When dividing 2971 by 778, we get 3 with a remainder of 637.
Use 3 as the next digit of our solution. 
Result so far: 79573.0
If we subtract 2334 from 2971, we get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Going ahead to step 9:
6370 divided by 778 is 8 with a remainder of 146.
Write down 8 as next digit of the result. 
Result so far: 79573.8
Deduct 6224 from 6370 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 10:
If we divide 1460 by 778, we get 1 and a remainder of 682.
Record the quotient 1 as the next digit in the result. 
Result so far: 79573.81
If we subtract 778 from 1460, we get 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

On to step 11:
When dividing 6820 by 778, we get 8 with a remainder of 596.
The number 8 becomes the next digit in our result. 
Result so far: 79573.818
Subtracting 6224 from 6820 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 12:
When dividing 5960 by 778, we get 7 with a remainder of 514.
The next digit of our result is 7. 
Result so far: 79573.8187
Deduct 5446 from 5960 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Going ahead to step 13:
The number 778 fits into 5140 6 times, leaving a remainder of 472.
Use 6 as the next digit of our solution. 
Result so far: 79573.81876
If we subtract 4668 from 5140, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 14:
4720 divided by 778 is 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 79573.818766
The remainder is 52 after subtracting 4668 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 79573.818766 with a remaining 5.2e-06.
