64138579 ÷ 942 
Our goal is to divide 64138579 by 942.

Advancing to step 1:
When dividing 6 by 942, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 942

Moving on to step 2:
942 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 942

Let's proceed to step 3:
The number 942 fits into 641 0 times, leaving a remainder of 641.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 641, we get 641.
Fetch the next digit (3) from the dividend, attach it to 641 and continue: 6413 / 942

Let's proceed to step 4:
942 can be fit into 6413 6 times, resulting in a remainder of 761.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 761 after subtracting 5652 from 6413.
Fetch the next digit (8) from the dividend, attach it to 761 and continue: 7618 / 942

Advancing to step 5:
The number 942 fits into 7618 8 times, leaving a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Deduct 7536 from 7618 and we're left with 82.
Fetch the next digit (5) from the dividend, attach it to 82 and continue: 825 / 942

Advancing to step 6:
When dividing 825 by 942, we get 0 with a remainder of 825.
Write down 0 as next digit of the result. 
Result so far: 680.0
Subtract 0 from 825 to get 825.
Grab the next digit (7) from the dividend, add it to 825, then carry on: 8257 / 942

Advancing to step 7:
8257 divided by 942 is 8 with a remainder of 721.
The next digit of our result is 8. 
Result so far: 6808.0
Subtract 7536 from 8257 to get 721.
Take the next digit (9) from the dividend and append it to 721, then repeat: 7219 / 942

Let's proceed to step 8:
942 can be fit into 7219 7 times, resulting in a remainder of 625.
The next digit of our result is 7. 
Result so far: 68087.0
If we take 6594 away from 7219, we end up with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Let's proceed to step 9:
If we divide 6250 by 942, we get 6 and a remainder of 598.
Record the quotient 6 as the next digit in the result. 
Result so far: 68087.6
Subtract 5652 from 6250 to get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Moving on to step 10:
If we divide 5980 by 942, we get 6 and a remainder of 328.
Put 6 as the next digit of the answer. 
Result so far: 68087.66
Subtract 5652 from 5980 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The final result is 68087.66 with a remainder of 0.328.
