We look at the division of 7870166 by 48 
We want to figure out the number of times 7870166 can be divided by 48.

Moving on to step 1:
The number 48 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 48

On to step 2:
78 divided by 48 is 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 48 from 78 leaves us with 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 48

Going ahead to step 3:
48 goes into 307 6 times with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 288 from 307, we get 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 48

Going ahead to step 4:
190 divided by 48 is 3 with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 163.0
Deduct 144 from 190 and we're left with 46.
Fetch the next digit (1) from the dividend, attach it to 46 and continue: 461 / 48

Step 5:
461 divided by 48 is 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 1639.0
Subtracting 432 from 461 leaves us with 29.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 48

Let's proceed to step 6:
If we divide 296 by 48, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 16396.0
If we take 288 away from 296, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 48

On to step 7:
86 divided by 48 is 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 163961.0
The remainder is 38 after subtracting 48 from 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
The number 48 fits into 380 7 times, leaving a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 163961.7
The remainder is 44 after subtracting 336 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
48 can be fit into 440 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 163961.79
Deduct 432 from 440 and we're left with 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 10:
When dividing 80 by 48, we get 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 163961.791
The remainder is 32 after subtracting 48 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
When dividing 320 by 48, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 163961.7916
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
48 can be fit into 320 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 163961.79166
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 163961.79166 with a remainder of 3.2e-05.
