Let's divide 77394523 by 39
We're looking to find how many times 39 goes into 77394523.

On to step 1:
39 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 39

Advancing to step 2:
77 divided by 39 is 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 38 after subtracting 39 from 77.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 39

Advancing to step 3:
When dividing 383 by 39, we get 9 with a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 351 from 383, we get 32.
Take the next digit (9) from the dividend and append it to 32, then repeat: 329 / 39

On to step 4:
When dividing 329 by 39, we get 8 with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 198.0
Subtract 312 from 329 to get 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 39

Step 5:
174 divided by 39 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 1984.0
The remainder is 18 after subtracting 156 from 174.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 39

Let's proceed to step 6:
39 can be fit into 185 4 times, resulting in a remainder of 29.
The next digit of our result is 4. 
Result so far: 19844.0
The remainder is 29 after subtracting 156 from 185.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 39

Advancing to step 7:
39 goes into 292 7 times with a remainder of 19.
The next digit of our result is 7. 
Result so far: 198447.0
Deduct 273 from 292 and we're left with 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 39

Let's proceed to step 8:
39 can be fit into 193 4 times, resulting in a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 1984474.0
Subtracting 156 from 193 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
39 can be fit into 370 9 times, resulting in a remainder of 19.
The next digit of our result is 9. 
Result so far: 1984474.9
If we subtract 351 from 370, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
190 divided by 39 is 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 1984474.94
Subtract 156 from 190 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
39 can be fit into 340 8 times, resulting in a remainder of 28.
The next digit of our result is 8. 
Result so far: 1984474.948
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
39 can be fit into 280 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 1984474.9487
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
When dividing 70 by 39, we get 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1984474.94871
Deduct 39 from 70 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 14:
39 goes into 310 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 1984474.948717
Subtracting 273 from 310 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 15:
When dividing 370 by 39, we get 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 1984474.9487179
Subtract 351 from 370 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 16:
190 divided by 39 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 1984474.94871794
Subtracting 156 from 190 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 1984474.94871794 with a remaining 3.4e-08.
