We look at the division of 71139429 by 577 
Our goal is to divide 71139429 by 577.

Moving on to step 1:
577 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 577

Advancing to step 2:
577 goes into 71 0 times with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Bring next digit (1) of the dividend behind the 71 and repeat the process: 711 / 577

Let's proceed to step 3:
577 can be fit into 711 1 times, resulting in a remainder of 134.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 577 from 711 leaves us with 134.
Include the next digit (3) from the dividend after 134, then repeat: 1343 / 577

Advancing to step 4:
When dividing 1343 by 577, we get 2 with a remainder of 189.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1154 from 1343, we get 189.
Bring next digit (9) of the dividend behind the 189 and repeat the process: 1899 / 577

Let's proceed to step 5:
577 can be fit into 1899 3 times, resulting in a remainder of 168.
The next digit of our result is 3. 
Result so far: 123.0
Deduct 1731 from 1899 and we're left with 168.
Bring next digit (4) of the dividend behind the 168 and repeat the process: 1684 / 577

Going ahead to step 6:
577 can be fit into 1684 2 times, resulting in a remainder of 530.
Use 2 as the next digit of our solution. 
Result so far: 1232.0
Subtract 1154 from 1684 to get 530.
Take the next digit (2) from the dividend and append it to 530, then repeat: 5302 / 577

Let's proceed to step 7:
The number 577 fits into 5302 9 times, leaving a remainder of 109.
The next digit of our result is 9. 
Result so far: 12329.0
Deduct 5193 from 5302 and we're left with 109.
Append the next digit (9) from the dividend to 109 and continue with: 1099 / 577

Moving on to step 8:
The number 577 fits into 1099 1 times, leaving a remainder of 522.
The next digit of our result is 1. 
Result so far: 123291.0
If we take 577 away from 1099, we end up with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

On to step 9:
577 can be fit into 5220 9 times, resulting in a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 123291.9
Subtract 5193 from 5220 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 10:
If we divide 270 by 577, we get 0 and a remainder of 270.
The next digit of our result is 0. 
Result so far: 123291.9
Deduct 0 from 270 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 11:
If we divide 2700 by 577, we get 4 and a remainder of 392.
The next digit of our result is 4. 
Result so far: 123291.904
Deduct 2308 from 2700 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 12:
577 goes into 3920 6 times with a remainder of 458.
Put 6 as the next digit of the answer. 
Result so far: 123291.9046
Subtracting 3462 from 3920 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 13:
577 can be fit into 4580 7 times, resulting in a remainder of 541.
Use 7 as the next digit of our solution. 
Result so far: 123291.90467
Subtract 4039 from 4580 to get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Moving on to step 14:
When dividing 5410 by 577, we get 9 with a remainder of 217.
The number 9 becomes the next digit in our result. 
Result so far: 123291.904679
Deduct 5193 from 5410 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 15:
If we divide 2170 by 577, we get 3 and a remainder of 439.
The number 3 becomes the next digit in our result. 
Result so far: 123291.9046793
Subtracting 1731 from 2170 leaves us with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Advancing to step 16:
If we divide 4390 by 577, we get 7 and a remainder of 351.
Use 7 as the next digit of our solution. 
Result so far: 123291.90467937
Subtracting 4039 from 4390 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

The quotient of the division is 123291.90467937, and the remainder is 3.51e-07.
