We're dividing 642990 by 47 
We want to figure out the number of times 642990 can be divided by 47.

On to step 1:
The number 47 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 47

Going ahead to step 2:
64 divided by 47 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 47 from 64, we get 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 47

On to step 3:
If we divide 172 by 47, we get 3 and a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 141 from 172, we get 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 47

Step 4:
319 divided by 47 is 6 with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
If we subtract 282 from 319, we get 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 47

Step 5:
47 can be fit into 379 8 times, resulting in a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 1368.0
Subtract 376 from 379 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 47

Advancing to step 6:
The number 47 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 13680.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
When dividing 300 by 47, we get 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 13680.6
If we take 282 away from 300, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
The number 47 fits into 180 3 times, leaving a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 13680.63
If we subtract 141 from 180, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
390 divided by 47 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 13680.638
The remainder is 14 after subtracting 376 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
When dividing 140 by 47, we get 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 13680.6382
If we take 94 away from 140, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
460 divided by 47 is 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 13680.63829
The remainder is 37 after subtracting 423 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 12:
When dividing 370 by 47, we get 7 with a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 13680.638297
Deduct 329 from 370 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 13:
47 can be fit into 410 8 times, resulting in a remainder of 34.
The next digit of our result is 8. 
Result so far: 13680.6382978
If we subtract 376 from 410, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 14:
47 goes into 340 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 13680.63829787
Subtract 329 from 340 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 13680.63829787 with a balance of 1.1e-08.
