We're dividing 47122291 by 642 
We want to divide 47122291 by 642.

Advancing to step 1:
642 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 642

Going ahead to step 2:
642 goes into 47 0 times with a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 642

Step 3:
642 can be fit into 471 0 times, resulting in a remainder of 471.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 471 to get 471.
Append the next digit (2) from the dividend to 471 and continue with: 4712 / 642

Step 4:
The number 642 fits into 4712 7 times, leaving a remainder of 218.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 4494 from 4712, we get 218.
Fetch the next digit (2) from the dividend, attach it to 218 and continue: 2182 / 642

Going ahead to step 5:
2182 divided by 642 is 3 with a remainder of 256.
The next digit of our result is 3. 
Result so far: 73.0
The remainder is 256 after subtracting 1926 from 2182.
Fetch the next digit (2) from the dividend, attach it to 256 and continue: 2562 / 642

On to step 6:
642 can be fit into 2562 3 times, resulting in a remainder of 636.
The number 3 becomes the next digit in our result. 
Result so far: 733.0
Deduct 1926 from 2562 and we're left with 636.
Include the next digit (9) from the dividend after 636, then repeat: 6369 / 642

On to step 7:
6369 divided by 642 is 9 with a remainder of 591.
Use 9 as the next digit of our solution. 
Result so far: 7339.0
If we take 5778 away from 6369, we end up with 591.
Fetch the next digit (1) from the dividend, attach it to 591 and continue: 5911 / 642

Step 8:
The number 642 fits into 5911 9 times, leaving a remainder of 133.
The number 9 becomes the next digit in our result. 
Result so far: 73399.0
Subtract 5778 from 5911 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 9:
The number 642 fits into 1330 2 times, leaving a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 73399.2
The remainder is 46 after subtracting 1284 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
The number 642 fits into 460 0 times, leaving a remainder of 460.
The next digit of our result is 0. 
Result so far: 73399.2
If we take 0 away from 460, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 11:
When dividing 4600 by 642, we get 7 with a remainder of 106.
Write down 7 as next digit of the result. 
Result so far: 73399.207
Subtracting 4494 from 4600 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 12:
642 goes into 1060 1 times with a remainder of 418.
The number 1 becomes the next digit in our result. 
Result so far: 73399.2071
The remainder is 418 after subtracting 642 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 13:
When dividing 4180 by 642, we get 6 with a remainder of 328.
Put 6 as the next digit of the answer. 
Result so far: 73399.20716
Deduct 3852 from 4180 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 14:
The number 642 fits into 3280 5 times, leaving a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 73399.207165
If we subtract 3210 from 3280, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 15:
642 can be fit into 700 1 times, resulting in a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 73399.2071651
Subtracting 642 from 700 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 16:
580 divided by 642 is 0 with a remainder of 580.
Record the quotient 0 as the next digit in the result. 
Result so far: 73399.2071651
Deduct 0 from 580 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

The final result is 73399.2071651 with a remainder of 5.8e-07.
