We look at the division of 76121568 by 434 
Let's see how many times 434 fits into 76121568.

Advancing to step 1:
If we divide 7 by 434, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 434

Let's proceed to step 2:
434 goes into 76 0 times with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Bring next digit (1) of the dividend behind the 76 and repeat the process: 761 / 434

Advancing to step 3:
434 can be fit into 761 1 times, resulting in a remainder of 327.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 327 after subtracting 434 from 761.
Fetch the next digit (2) from the dividend, attach it to 327 and continue: 3272 / 434

Moving on to step 4:
3272 divided by 434 is 7 with a remainder of 234.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 3038 away from 3272, we end up with 234.
Take the next digit (1) from the dividend and append it to 234, then repeat: 2341 / 434

Let's proceed to step 5:
2341 divided by 434 is 5 with a remainder of 171.
Write down 5 as next digit of the result. 
Result so far: 175.0
If we subtract 2170 from 2341, we get 171.
Include the next digit (5) from the dividend after 171, then repeat: 1715 / 434

Going ahead to step 6:
The number 434 fits into 1715 3 times, leaving a remainder of 413.
Use 3 as the next digit of our solution. 
Result so far: 1753.0
If we subtract 1302 from 1715, we get 413.
Bring next digit (6) of the dividend behind the 413 and repeat the process: 4136 / 434

Let's proceed to step 7:
434 goes into 4136 9 times with a remainder of 230.
Record the quotient 9 as the next digit in the result. 
Result so far: 17539.0
Subtracting 3906 from 4136 leaves us with 230.
Take the next digit (8) from the dividend and append it to 230, then repeat: 2308 / 434

Advancing to step 8:
2308 divided by 434 is 5 with a remainder of 138.
Use 5 as the next digit of our solution. 
Result so far: 175395.0
If we take 2170 away from 2308, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 9:
The number 434 fits into 1380 3 times, leaving a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 175395.3
Subtract 1302 from 1380 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
When dividing 780 by 434, we get 1 with a remainder of 346.
Write down 1 as next digit of the result. 
Result so far: 175395.31
If we take 434 away from 780, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 11:
If we divide 3460 by 434, we get 7 and a remainder of 422.
The number 7 becomes the next digit in our result. 
Result so far: 175395.317
Subtract 3038 from 3460 to get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 12:
4220 divided by 434 is 9 with a remainder of 314.
The next digit of our result is 9. 
Result so far: 175395.3179
If we take 3906 away from 4220, we end up 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.

Advancing to step 13:
434 can be fit into 3140 7 times, resulting in a remainder of 102.
Record the quotient 7 as the next digit in the result. 
Result so far: 175395.31797
Subtract 3038 from 3140 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 14:
When dividing 1020 by 434, we get 2 with a remainder of 152.
The next digit of our result is 2. 
Result so far: 175395.317972
Subtract 868 from 1020 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 15:
The number 434 fits into 1520 3 times, leaving a remainder of 218.
Use 3 as the next digit of our solution. 
Result so far: 175395.3179723
Deduct 1302 from 1520 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 16:
If we divide 2180 by 434, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 175395.31797235
If we take 2170 away from 2180, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 175395.31797235 with a balance of 1e-08.
