68457659 ÷ 978 
We want to figure out the number of times 68457659 can be divided by 978.

Step 1:
978 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 978

Step 2:
978 goes into 68 0 times with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Take the next digit (4) from the dividend and append it to 68, then repeat: 684 / 978

Step 3:
The number 978 fits into 684 0 times, leaving a remainder of 684.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 684, we get 684.
Bring next digit (5) of the dividend behind the 684 and repeat the process: 6845 / 978

On to step 4:
978 goes into 6845 6 times with a remainder of 977.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 5868 from 6845, we get 977.
Take the next digit (7) from the dividend and append it to 977, then repeat: 9777 / 978

Going ahead to step 5:
9777 divided by 978 is 9 with a remainder of 975.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
The remainder is 975 after subtracting 8802 from 9777.
Take the next digit (6) from the dividend and append it to 975, then repeat: 9756 / 978

Moving on to step 6:
978 goes into 9756 9 times with a remainder of 954.
Use 9 as the next digit of our solution. 
Result so far: 699.0
Deduct 8802 from 9756 and we're left with 954.
Take the next digit (5) from the dividend and append it to 954, then repeat: 9545 / 978

Moving on to step 7:
978 can be fit into 9545 9 times, resulting in a remainder of 743.
The number 9 becomes the next digit in our result. 
Result so far: 6999.0
Deduct 8802 from 9545 and we're left with 743.
Bring next digit (9) of the dividend behind the 743 and repeat the process: 7439 / 978

On to step 8:
7439 divided by 978 is 7 with a remainder of 593.
The number 7 becomes the next digit in our result. 
Result so far: 69997.0
Deduct 6846 from 7439 and we're left with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Step 9:
If we divide 5930 by 978, we get 6 and a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 69997.6
Subtracting 5868 from 5930 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
When dividing 620 by 978, we get 0 with a remainder of 620.
Record the quotient 0 as the next digit in the result. 
Result so far: 69997.6
Subtracting 0 from 620 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 11:
When dividing 6200 by 978, we get 6 with a remainder of 332.
Write down 6 as next digit of the result. 
Result so far: 69997.606
If we take 5868 away from 6200, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 12:
978 goes into 3320 3 times with a remainder of 386.
The number 3 becomes the next digit in our result. 
Result so far: 69997.6063
The remainder is 386 after subtracting 2934 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 13:
3860 divided by 978 is 3 with a remainder of 926.
The number 3 becomes the next digit in our result. 
Result so far: 69997.60633
If we take 2934 away from 3860, we end up with 926.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9260, and continue the process.

The final outcome is 69997.60633, with a leftover of 0.000926.
