We look at the division of 763141 by 39 
We want to figure out the number of times 763141 can be divided by 39.

Step 1:
39 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 39

Step 2:
If we divide 76 by 39, we get 1 and a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 39 from 76 leaves us with 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 39

Step 3:
If we divide 373 by 39, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 351 from 373 to get 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 39

Moving on to step 4:
When dividing 221 by 39, we get 5 with a remainder of 26.
The next digit of our result is 5. 
Result so far: 195.0
Subtract 195 from 221 to get 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 39

Advancing to step 5:
39 goes into 264 6 times with a remainder of 30.
The next digit of our result is 6. 
Result so far: 1956.0
If we take 234 away from 264, we end up with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 39

On to step 6:
If we divide 301 by 39, we get 7 and a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 19567.0
If we take 273 away from 301, we end up 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 7:
If we divide 280 by 39, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 19567.7
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
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: 19567.71
The remainder is 31 after subtracting 39 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
The number 39 fits into 310 7 times, leaving a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 19567.717
The remainder is 37 after subtracting 273 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
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: 19567.7179
If we take 351 away from 370, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
190 divided by 39 is 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 19567.71794
If we take 156 away from 190, we end up 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.

Let's proceed to step 12:
When dividing 340 by 39, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 19567.717948
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.

On to step 13:
39 goes into 280 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 19567.7179487
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.

Going ahead to step 14:
The number 39 fits into 70 1 times, leaving a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 19567.71794871
Subtract 39 from 70 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 19567.71794871 with a remaining 3.1e-08.
