We look at the division of 64519511 by 939 
We want to figure out the number of times 64519511 can be divided by 939.

Let's proceed to step 1:
939 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 939

Advancing to step 2:
When dividing 64 by 939, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 939

Advancing to step 3:
939 goes into 645 0 times with a remainder of 645.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 645, we get 645.
Grab the next digit (1) from the dividend, add it to 645, then carry on: 6451 / 939

Going ahead to step 4:
939 can be fit into 6451 6 times, resulting in a remainder of 817.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 5634 away from 6451, we end up with 817.
Include the next digit (9) from the dividend after 817, then repeat: 8179 / 939

Moving on to step 5:
The number 939 fits into 8179 8 times, leaving a remainder of 667.
Write down 8 as next digit of the result. 
Result so far: 68.0
Deduct 7512 from 8179 and we're left with 667.
Fetch the next digit (5) from the dividend, attach it to 667 and continue: 6675 / 939

Going ahead to step 6:
The number 939 fits into 6675 7 times, leaving a remainder of 102.
The next digit of our result is 7. 
Result so far: 687.0
Deduct 6573 from 6675 and we're left with 102.
Append the next digit (1) from the dividend to 102 and continue with: 1021 / 939

Advancing to step 7:
The number 939 fits into 1021 1 times, leaving a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 6871.0
If we take 939 away from 1021, we end up with 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 939

Moving on to step 8:
939 can be fit into 821 0 times, resulting in a remainder of 821.
The number 0 becomes the next digit in our result. 
Result so far: 68710.0
Subtract 0 from 821 to get 821.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

Step 9:
When dividing 8210 by 939, we get 8 with a remainder of 698.
Write down 8 as next digit of the result. 
Result so far: 68710.8
The remainder is 698 after subtracting 7512 from 8210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Advancing to step 10:
The number 939 fits into 6980 7 times, leaving a remainder of 407.
The number 7 becomes the next digit in our result. 
Result so far: 68710.87
Subtracting 6573 from 6980 leaves us with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Step 11:
939 goes into 4070 4 times with a remainder of 314.
The next digit of our result is 4. 
Result so far: 68710.874
Subtracting 3756 from 4070 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 12:
939 goes into 3140 3 times with a remainder of 323.
Put 3 as the next digit of the answer. 
Result so far: 68710.8743
Subtract 2817 from 3140 to get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Going ahead to step 13:
939 goes into 3230 3 times with a remainder of 413.
Write down 3 as next digit of the result. 
Result so far: 68710.87433
Deduct 2817 from 3230 and we're left with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

The final result is 68710.87433 with a remainder of 0.000413.
