We look at the division of 77430057 by 953 
Our goal is to divide 77430057 by 953.

Going ahead to step 1:
953 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 953

On to step 2:
The number 953 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 953

Step 3:
If we divide 774 by 953, we get 0 and a remainder of 774.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 774 leaves us with 774.
Append the next digit (3) from the dividend to 774 and continue with: 7743 / 953

Moving on to step 4:
953 can be fit into 7743 8 times, resulting in a remainder of 119.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 7624 from 7743, we get 119.
Fetch the next digit (0) from the dividend, attach it to 119 and continue: 1190 / 953

Moving on to step 5:
When dividing 1190 by 953, we get 1 with a remainder of 237.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we subtract 953 from 1190, we get 237.
Append the next digit (0) from the dividend to 237 and continue with: 2370 / 953

Let's proceed to step 6:
953 goes into 2370 2 times with a remainder of 464.
Put 2 as the next digit of the answer. 
Result so far: 812.0
Deduct 1906 from 2370 and we're left with 464.
Grab the next digit (5) from the dividend, add it to 464, then carry on: 4645 / 953

Step 7:
The number 953 fits into 4645 4 times, leaving a remainder of 833.
The number 4 becomes the next digit in our result. 
Result so far: 8124.0
Subtracting 3812 from 4645 leaves us with 833.
Grab the next digit (7) from the dividend, add it to 833, then carry on: 8337 / 953

Advancing to step 8:
If we divide 8337 by 953, we get 8 and a remainder of 713.
Use 8 as the next digit of our solution. 
Result so far: 81248.0
Deduct 7624 from 8337 and we're left with 713.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

Going ahead to step 9:
953 can be fit into 7130 7 times, resulting in a remainder of 459.
Put 7 as the next digit of the answer. 
Result so far: 81248.7
If we subtract 6671 from 7130, we get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Advancing to step 10:
953 goes into 4590 4 times with a remainder of 778.
The number 4 becomes the next digit in our result. 
Result so far: 81248.74
The remainder is 778 after subtracting 3812 from 4590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Advancing to step 11:
If we divide 7780 by 953, we get 8 and a remainder of 156.
Record the quotient 8 as the next digit in the result. 
Result so far: 81248.748
Deduct 7624 from 7780 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 12:
The number 953 fits into 1560 1 times, leaving a remainder of 607.
The next digit of our result is 1. 
Result so far: 81248.7481
Subtracting 953 from 1560 leaves us with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Going ahead to step 13:
The number 953 fits into 6070 6 times, leaving a remainder of 352.
The next digit of our result is 6. 
Result so far: 81248.74816
If we take 5718 away from 6070, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 14:
3520 divided by 953 is 3 with a remainder of 661.
Use 3 as the next digit of our solution. 
Result so far: 81248.748163
The remainder is 661 after subtracting 2859 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Advancing to step 15:
When dividing 6610 by 953, we get 6 with a remainder of 892.
Write down 6 as next digit of the result. 
Result so far: 81248.7481636
If we subtract 5718 from 6610, we get 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

Moving on to step 16:
The number 953 fits into 8920 9 times, leaving a remainder of 343.
The next digit of our result is 9. 
Result so far: 81248.74816369
If we take 8577 away from 8920, we end up with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

The final result is 81248.74816369 with a remainder of 3.43e-07.
