12837957 divided by 773 
Let's see how many times 773 fits into 12837957.

On to step 1:
773 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 773

On to step 2:
If we divide 12 by 773, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 773

Advancing to step 3:
128 divided by 773 is 0 with a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 128 leaves us with 128.
Grab the next digit (3) from the dividend, add it to 128, then carry on: 1283 / 773

Moving on to step 4:
773 goes into 1283 1 times with a remainder of 510.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 773 from 1283 to get 510.
Bring next digit (7) of the dividend behind the 510 and repeat the process: 5107 / 773

Moving on to step 5:
5107 divided by 773 is 6 with a remainder of 469.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 4638 from 5107 to get 469.
Fetch the next digit (9) from the dividend, attach it to 469 and continue: 4699 / 773

Going ahead to step 6:
When dividing 4699 by 773, we get 6 with a remainder of 61.
The next digit of our result is 6. 
Result so far: 166.0
If we take 4638 away from 4699, we end up with 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 773

Advancing to step 7:
773 goes into 615 0 times with a remainder of 615.
The number 0 becomes the next digit in our result. 
Result so far: 1660.0
If we subtract 0 from 615, we get 615.
Include the next digit (7) from the dividend after 615, then repeat: 6157 / 773

Going ahead to step 8:
The number 773 fits into 6157 7 times, leaving a remainder of 746.
Record the quotient 7 as the next digit in the result. 
Result so far: 16607.0
Subtracting 5411 from 6157 leaves us with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

On to step 9:
773 can be fit into 7460 9 times, resulting in a remainder of 503.
Record the quotient 9 as the next digit in the result. 
Result so far: 16607.9
Deduct 6957 from 7460 and we're left with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Step 10:
The number 773 fits into 5030 6 times, leaving a remainder of 392.
Use 6 as the next digit of our solution. 
Result so far: 16607.96
If we subtract 4638 from 5030, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 11:
When dividing 3920 by 773, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 16607.965
The remainder is 55 after subtracting 3865 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 12:
773 can be fit into 550 0 times, resulting in a remainder of 550.
The number 0 becomes the next digit in our result. 
Result so far: 16607.965
Deduct 0 from 550 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 13:
If we divide 5500 by 773, we get 7 and a remainder of 89.
Write down 7 as next digit of the result. 
Result so far: 16607.96507
Subtracting 5411 from 5500 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 14:
773 goes into 890 1 times with a remainder of 117.
The number 1 becomes the next digit in our result. 
Result so far: 16607.965071
Deduct 773 from 890 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 15:
If we divide 1170 by 773, we get 1 and a remainder of 397.
The number 1 becomes the next digit in our result. 
Result so far: 16607.9650711
If we take 773 away from 1170, we end up with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

The final result is 16607.9650711 with a remainder of 3.97e-06.
