We look at the division of 57210972 by 775 
Let's see how many times 775 fits into 57210972.

Advancing to step 1:
The number 775 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 775

On to step 2:
775 can be fit into 57 0 times, resulting in a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 775

On to step 3:
775 can be fit into 572 0 times, resulting in a remainder of 572.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 572, we end up with 572.
Fetch the next digit (1) from the dividend, attach it to 572 and continue: 5721 / 775

Step 4:
If we divide 5721 by 775, we get 7 and a remainder of 296.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 5425 from 5721 and we're left with 296.
Include the next digit (0) from the dividend after 296, then repeat: 2960 / 775

Going ahead to step 5:
The number 775 fits into 2960 3 times, leaving a remainder of 635.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtract 2325 from 2960 to get 635.
Grab the next digit (9) from the dividend, add it to 635, then carry on: 6359 / 775

On to step 6:
When dividing 6359 by 775, we get 8 with a remainder of 159.
Put 8 as the next digit of the answer. 
Result so far: 738.0
If we take 6200 away from 6359, we end up with 159.
Take the next digit (7) from the dividend and append it to 159, then repeat: 1597 / 775

Step 7:
1597 divided by 775 is 2 with a remainder of 47.
The next digit of our result is 2. 
Result so far: 7382.0
The remainder is 47 after subtracting 1550 from 1597.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 775

On to step 8:
When dividing 472 by 775, we get 0 with a remainder of 472.
Use 0 as the next digit of our solution. 
Result so far: 73820.0
The remainder is 472 after subtracting 0 from 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 9:
775 goes into 4720 6 times with a remainder of 70.
The next digit of our result is 6. 
Result so far: 73820.6
If we take 4650 away from 4720, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
775 can be fit into 700 0 times, resulting in a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 73820.6
Deduct 0 from 700 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 11:
If we divide 7000 by 775, we get 9 and a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 73820.609
If we take 6975 away from 7000, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
775 can be fit into 250 0 times, resulting in a remainder of 250.
The next digit of our result is 0. 
Result so far: 73820.609
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 13:
If we divide 2500 by 775, we get 3 and a remainder of 175.
Put 3 as the next digit of the answer. 
Result so far: 73820.60903
Subtracting 2325 from 2500 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 14:
When dividing 1750 by 775, we get 2 with a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 73820.609032
Subtracting 1550 from 1750 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 15:
775 goes into 2000 2 times with a remainder of 450.
Write down 2 as next digit of the result. 
Result so far: 73820.6090322
Deduct 1550 from 2000 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

The final outcome is 73820.6090322, with a leftover of 4.5e-06.
