42155600 divided by 979 
Let's see how many times 979 fits into 42155600.

Let's proceed to step 1:
The number 979 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 979

On to step 2:
979 goes into 42 0 times with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 979

Advancing to step 3:
If we divide 421 by 979, we get 0 and a remainder of 421.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 421 leaves us with 421.
Take the next digit (5) from the dividend and append it to 421, then repeat: 4215 / 979

Step 4:
When dividing 4215 by 979, we get 4 with a remainder of 299.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3916 away from 4215, we end up with 299.
Bring next digit (5) of the dividend behind the 299 and repeat the process: 2995 / 979

Going ahead to step 5:
When dividing 2995 by 979, we get 3 with a remainder of 58.
The next digit of our result is 3. 
Result so far: 43.0
Subtracting 2937 from 2995 leaves us with 58.
Fetch the next digit (6) from the dividend, attach it to 58 and continue: 586 / 979

Let's proceed to step 6:
979 can be fit into 586 0 times, resulting in a remainder of 586.
Write down 0 as next digit of the result. 
Result so far: 430.0
If we subtract 0 from 586, we get 586.
Bring next digit (0) of the dividend behind the 586 and repeat the process: 5860 / 979

Going ahead to step 7:
979 goes into 5860 5 times with a remainder of 965.
Record the quotient 5 as the next digit in the result. 
Result so far: 4305.0
Deduct 4895 from 5860 and we're left with 965.
Take the next digit (0) from the dividend and append it to 965, then repeat: 9650 / 979

Going ahead to step 8:
When dividing 9650 by 979, we get 9 with a remainder of 839.
Use 9 as the next digit of our solution. 
Result so far: 43059.0
Deduct 8811 from 9650 and we're left with 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8390, and continue the process.

Moving on to step 9:
The number 979 fits into 8390 8 times, leaving a remainder of 558.
Write down 8 as next digit of the result. 
Result so far: 43059.8
Deduct 7832 from 8390 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 10:
If we divide 5580 by 979, we get 5 and a remainder of 685.
Record the quotient 5 as the next digit in the result. 
Result so far: 43059.85
Deduct 4895 from 5580 and we're left with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Step 11:
979 can be fit into 6850 6 times, resulting in a remainder of 976.
The number 6 becomes the next digit in our result. 
Result so far: 43059.856
Subtracting 5874 from 6850 leaves us with 976.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9760, and continue the process.

On to step 12:
9760 divided by 979 is 9 with a remainder of 949.
The number 9 becomes the next digit in our result. 
Result so far: 43059.8569
The remainder is 949 after subtracting 8811 from 9760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9490, and continue the process.

Step 13:
When dividing 9490 by 979, we get 9 with a remainder of 679.
Write down 9 as next digit of the result. 
Result so far: 43059.85699
If we subtract 8811 from 9490, we get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

After the division, we end up with 43059.85699 and a remainder of 0.000679.
