745778 ÷ 39 
We want to figure out the number of times 745778 can be divided by 39.

On to step 1:
7 divided by 39 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 39

Step 2:
39 goes into 74 1 times with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 39 from 74 to get 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 39

Advancing to step 3:
39 goes into 355 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 351 from 355 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 39

Going ahead to step 4:
39 can be fit into 47 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 191.0
If we subtract 39 from 47, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 39

Step 5:
The number 39 fits into 87 2 times, leaving a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 1912.0
Subtracting 78 from 87 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 39

Step 6:
39 goes into 98 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 19122.0
The remainder is 20 after subtracting 78 from 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
200 divided by 39 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 19122.5
Subtracting 195 from 200 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 39, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 19122.51
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
When dividing 110 by 39, we get 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 19122.512
Deduct 78 from 110 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
When dividing 320 by 39, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 19122.5128
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
If we divide 80 by 39, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 19122.51282
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
If we divide 20 by 39, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 19122.51282
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
39 can be fit into 200 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 19122.5128205
Subtracting 195 from 200 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
50 divided by 39 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 19122.51282051
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 19122.51282051, and the remainder is 1.1e-08.
