We look at the division of 19887455 by 679 
We want to divide 19887455 by 679.

Going ahead to step 1:
679 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
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 679

On to step 2:
The number 679 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 679

Moving on to step 3:
679 goes into 198 0 times with a remainder of 198.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 198, we get 198.
Take the next digit (8) from the dividend and append it to 198, then repeat: 1988 / 679

On to step 4:
679 goes into 1988 2 times with a remainder of 630.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1358 from 1988 leaves us with 630.
Grab the next digit (7) from the dividend, add it to 630, then carry on: 6307 / 679

Advancing to step 5:
679 goes into 6307 9 times with a remainder of 196.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 6111 from 6307 and we're left with 196.
Bring next digit (4) of the dividend behind the 196 and repeat the process: 1964 / 679

Step 6:
679 goes into 1964 2 times with a remainder of 606.
Write down 2 as next digit of the result. 
Result so far: 292.0
Subtract 1358 from 1964 to get 606.
Grab the next digit (5) from the dividend, add it to 606, then carry on: 6065 / 679

Moving on to step 7:
When dividing 6065 by 679, we get 8 with a remainder of 633.
Record the quotient 8 as the next digit in the result. 
Result so far: 2928.0
Deduct 5432 from 6065 and we're left with 633.
Take the next digit (5) from the dividend and append it to 633, then repeat: 6335 / 679

Step 8:
If we divide 6335 by 679, we get 9 and a remainder of 224.
Put 9 as the next digit of the answer. 
Result so far: 29289.0
Deduct 6111 from 6335 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 9:
2240 divided by 679 is 3 with a remainder of 203.
Put 3 as the next digit of the answer. 
Result so far: 29289.3
If we take 2037 away from 2240, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 10:
When dividing 2030 by 679, we get 2 with a remainder of 672.
Use 2 as the next digit of our solution. 
Result so far: 29289.32
If we take 1358 away from 2030, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Advancing to step 11:
When dividing 6720 by 679, we get 9 with a remainder of 609.
The next digit of our result is 9. 
Result so far: 29289.329
Subtracting 6111 from 6720 leaves us with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Moving on to step 12:
6090 divided by 679 is 8 with a remainder of 658.
Record the quotient 8 as the next digit in the result. 
Result so far: 29289.3298
Subtract 5432 from 6090 to get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Going ahead to step 13:
6580 divided by 679 is 9 with a remainder of 469.
Use 9 as the next digit of our solution. 
Result so far: 29289.32989
The remainder is 469 after subtracting 6111 from 6580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Moving on to step 14:
When dividing 4690 by 679, we get 6 with a remainder of 616.
Record the quotient 6 as the next digit in the result. 
Result so far: 29289.329896
If we subtract 4074 from 4690, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Going ahead to step 15:
679 can be fit into 6160 9 times, resulting in a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 29289.3298969
Subtracting 6111 from 6160 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 16:
679 can be fit into 490 0 times, resulting in a remainder of 490.
Put 0 as the next digit of the answer. 
Result so far: 29289.3298969
If we subtract 0 from 490, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

The final result is 29289.3298969 with a remainder of 4.9e-07.
