We look at the division of 210948 by 40 
We're looking to find how many times 40 goes into 210948.

Advancing to step 1:
If we divide 2 by 40, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 40

On to step 2:
The number 40 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 40

Going ahead to step 3:
40 goes into 210 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 200 from 210 to get 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 40

Advancing to step 4:
The number 40 fits into 109 2 times, leaving a remainder of 29.
The next digit of our result is 2. 
Result so far: 52.0
Deduct 80 from 109 and we're left with 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 40

Step 5:
The number 40 fits into 294 7 times, leaving a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 527.0
Subtract 280 from 294 to get 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 40

Advancing to step 6:
148 divided by 40 is 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 5273.0
If we take 120 away from 148, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
If we divide 280 by 40, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 5273.7
The remainder is 0 after subtracting 280 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
40 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5273.7
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5273.7
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 5273.7, with a leftover of 0.0.
