48087158 ÷ 670 
Our goal is to divide 48087158 by 670.

Going ahead to step 1:
The number 670 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 670

On to step 2:
If we divide 48 by 670, we get 0 and a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 670

Going ahead to step 3:
When dividing 480 by 670, we get 0 with a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 480 and we're left with 480.
Bring next digit (8) of the dividend behind the 480 and repeat the process: 4808 / 670

Going ahead to step 4:
670 goes into 4808 7 times with a remainder of 118.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 4690 from 4808, we get 118.
Grab the next digit (7) from the dividend, add it to 118, then carry on: 1187 / 670

Let's proceed to step 5:
The number 670 fits into 1187 1 times, leaving a remainder of 517.
The next digit of our result is 1. 
Result so far: 71.0
If we subtract 670 from 1187, we get 517.
Append the next digit (1) from the dividend to 517 and continue with: 5171 / 670

Moving on to step 6:
The number 670 fits into 5171 7 times, leaving a remainder of 481.
Record the quotient 7 as the next digit in the result. 
Result so far: 717.0
If we subtract 4690 from 5171, we get 481.
Append the next digit (5) from the dividend to 481 and continue with: 4815 / 670

Step 7:
4815 divided by 670 is 7 with a remainder of 125.
The number 7 becomes the next digit in our result. 
Result so far: 7177.0
If we subtract 4690 from 4815, we get 125.
Bring next digit (8) of the dividend behind the 125 and repeat the process: 1258 / 670

Let's proceed to step 8:
670 goes into 1258 1 times with a remainder of 588.
Record the quotient 1 as the next digit in the result. 
Result so far: 71771.0
Deduct 670 from 1258 and we're left with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

On to step 9:
If we divide 5880 by 670, we get 8 and a remainder of 520.
The next digit of our result is 8. 
Result so far: 71771.8
Subtracting 5360 from 5880 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 10:
670 can be fit into 5200 7 times, resulting in a remainder of 510.
Put 7 as the next digit of the answer. 
Result so far: 71771.87
Deduct 4690 from 5200 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 11:
If we divide 5100 by 670, we get 7 and a remainder of 410.
Record the quotient 7 as the next digit in the result. 
Result so far: 71771.877
Subtracting 4690 from 5100 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

The final outcome is 71771.877, with a leftover of 0.041.
