We look at the division of 28407430 by 977 
Our goal is to divide 28407430 by 977.

On to step 1:
If we divide 2 by 977, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 977

On to step 2:
977 goes into 28 0 times with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 977

Going ahead to step 3:
If we divide 284 by 977, we get 0 and a remainder of 284.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 284, we get 284.
Include the next digit (0) from the dividend after 284, then repeat: 2840 / 977

Going ahead to step 4:
When dividing 2840 by 977, we get 2 with a remainder of 886.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1954 from 2840, we get 886.
Grab the next digit (7) from the dividend, add it to 886, then carry on: 8867 / 977

Advancing to step 5:
977 goes into 8867 9 times with a remainder of 74.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtract 8793 from 8867 to get 74.
Append the next digit (4) from the dividend to 74 and continue with: 744 / 977

Moving on to step 6:
977 goes into 744 0 times with a remainder of 744.
The next digit of our result is 0. 
Result so far: 290.0
If we subtract 0 from 744, we get 744.
Append the next digit (3) from the dividend to 744 and continue with: 7443 / 977

Advancing to step 7:
977 goes into 7443 7 times with a remainder of 604.
Record the quotient 7 as the next digit in the result. 
Result so far: 2907.0
Subtracting 6839 from 7443 leaves us with 604.
Fetch the next digit (0) from the dividend, attach it to 604 and continue: 6040 / 977

On to step 8:
If we divide 6040 by 977, we get 6 and a remainder of 178.
Record the quotient 6 as the next digit in the result. 
Result so far: 29076.0
If we take 5862 away from 6040, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 9:
The number 977 fits into 1780 1 times, leaving a remainder of 803.
Record the quotient 1 as the next digit in the result. 
Result so far: 29076.1
If we subtract 977 from 1780, we get 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

Step 10:
977 can be fit into 8030 8 times, resulting in a remainder of 214.
Use 8 as the next digit of our solution. 
Result so far: 29076.18
Subtracting 7816 from 8030 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 11:
When dividing 2140 by 977, we get 2 with a remainder of 186.
Use 2 as the next digit of our solution. 
Result so far: 29076.182
If we take 1954 away from 2140, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 12:
977 can be fit into 1860 1 times, resulting in a remainder of 883.
Put 1 as the next digit of the answer. 
Result so far: 29076.1821
The remainder is 883 after subtracting 977 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8830, and continue the process.

Moving on to step 13:
977 can be fit into 8830 9 times, resulting in a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 29076.18219
The remainder is 37 after subtracting 8793 from 8830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 14:
977 goes into 370 0 times with a remainder of 370.
Write down 0 as next digit of the result. 
Result so far: 29076.18219
If we subtract 0 from 370, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 15:
977 can be fit into 3700 3 times, resulting in a remainder of 769.
The next digit of our result is 3. 
Result so far: 29076.1821903
If we take 2931 away from 3700, we end up with 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

On to step 16:
If we divide 7690 by 977, we get 7 and a remainder of 851.
Use 7 as the next digit of our solution. 
Result so far: 29076.18219037
The remainder is 851 after subtracting 6839 from 7690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

After the division, we end up with 29076.18219037 and a remainder of 8.51e-07.
