We look at the division of 420820 by 47 
We're looking to find how many times 47 goes into 420820.

Step 1:
If we divide 4 by 47, we get 0 and 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 (2) from the dividend, add it to 4, then carry on: 42 / 47

Let's proceed to step 2:
When dividing 42 by 47, we get 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 47

Going ahead to step 3:
47 can be fit into 420 8 times, resulting in a remainder of 44.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 376 from 420, we get 44.
Include the next digit (8) from the dividend after 44, then repeat: 448 / 47

On to step 4:
If we divide 448 by 47, we get 9 and a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtracting 423 from 448 leaves us with 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 47

Advancing to step 5:
252 divided by 47 is 5 with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 895.0
The remainder is 17 after subtracting 235 from 252.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 47

On to step 6:
When dividing 170 by 47, we get 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 8953.0
If we take 141 away from 170, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
47 goes into 290 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 8953.6
Subtract 282 from 290 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
If we divide 80 by 47, we get 1 and a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 8953.61
Deduct 47 from 80 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
47 goes into 330 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 8953.617
If we take 329 away from 330, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
47 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 8953.617
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
47 can be fit into 100 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 8953.61702
The remainder is 6 after subtracting 94 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
When dividing 60 by 47, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 8953.617021
Subtracting 47 from 60 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 13:
47 goes into 130 2 times with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 8953.6170212
Deduct 94 from 130 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
The number 47 fits into 360 7 times, leaving a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 8953.61702127
Deduct 329 from 360 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

After the division, we end up with 8953.61702127 and a remainder of 3.1e-08.
