Let's divide 29979553 by 642
We're looking to find how many times 642 goes into 29979553.

Advancing to step 1:
When dividing 2 by 642, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 642

Step 2:
642 can be fit into 29 0 times, resulting in a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 642

On to step 3:
642 can be fit into 299 0 times, resulting in a remainder of 299.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 299 after subtracting 0 from 299.
Take the next digit (7) from the dividend and append it to 299, then repeat: 2997 / 642

Going ahead to step 4:
When dividing 2997 by 642, we get 4 with a remainder of 429.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 2568 away from 2997, we end up with 429.
Append the next digit (9) from the dividend to 429 and continue with: 4299 / 642

Moving on to step 5:
The number 642 fits into 4299 6 times, leaving a remainder of 447.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we subtract 3852 from 4299, we get 447.
Fetch the next digit (5) from the dividend, attach it to 447 and continue: 4475 / 642

Step 6:
642 goes into 4475 6 times with a remainder of 623.
Record the quotient 6 as the next digit in the result. 
Result so far: 466.0
Deduct 3852 from 4475 and we're left with 623.
Grab the next digit (5) from the dividend, add it to 623, then carry on: 6235 / 642

Let's proceed to step 7:
642 goes into 6235 9 times with a remainder of 457.
The number 9 becomes the next digit in our result. 
Result so far: 4669.0
If we subtract 5778 from 6235, we get 457.
Grab the next digit (3) from the dividend, add it to 457, then carry on: 4573 / 642

Advancing to step 8:
The number 642 fits into 4573 7 times, leaving a remainder of 79.
Record the quotient 7 as the next digit in the result. 
Result so far: 46697.0
If we subtract 4494 from 4573, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
The number 642 fits into 790 1 times, leaving a remainder of 148.
Put 1 as the next digit of the answer. 
Result so far: 46697.1
Subtract 642 from 790 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 10:
If we divide 1480 by 642, we get 2 and a remainder of 196.
The number 2 becomes the next digit in our result. 
Result so far: 46697.12
Subtracting 1284 from 1480 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 11:
The number 642 fits into 1960 3 times, leaving a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 46697.123
The remainder is 34 after subtracting 1926 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
The number 642 fits into 340 0 times, leaving a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 46697.123
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 13:
642 goes into 3400 5 times with a remainder of 190.
Use 5 as the next digit of our solution. 
Result so far: 46697.12305
Deduct 3210 from 3400 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 14:
When dividing 1900 by 642, we get 2 with a remainder of 616.
Record the quotient 2 as the next digit in the result. 
Result so far: 46697.123052
Deduct 1284 from 1900 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 15:
642 goes into 6160 9 times with a remainder of 382.
The next digit of our result is 9. 
Result so far: 46697.1230529
Subtracting 5778 from 6160 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Let's proceed to step 16:
When dividing 3820 by 642, we get 5 with a remainder of 610.
The next digit of our result is 5. 
Result so far: 46697.12305295
Subtract 3210 from 3820 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

In conclusion, the division gives 46697.12305295 with a balance of 6.1e-07.
