15749620 ÷ 71 
We're looking to find how many times 71 goes into 15749620.

Going ahead to step 1:
When dividing 1 by 71, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 71

Let's proceed to step 2:
The number 71 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 71

Step 3:
71 goes into 157 2 times with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 142 from 157 leaves us with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 71

Moving on to step 4:
71 goes into 154 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 142 from 154 to get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 71

On to step 5:
71 goes into 129 1 times with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
The remainder is 58 after subtracting 71 from 129.
Grab the next digit (6) from the dividend, add it to 58, then carry on: 586 / 71

Moving on to step 6:
586 divided by 71 is 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 2218.0
The remainder is 18 after subtracting 568 from 586.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 71

Let's proceed to step 7:
The number 71 fits into 182 2 times, leaving a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 22182.0
The remainder is 40 after subtracting 142 from 182.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 71

Moving on to step 8:
If we divide 400 by 71, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 221825.0
Subtract 355 from 400 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
71 can be fit into 450 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 221825.6
The remainder is 24 after subtracting 426 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
When dividing 240 by 71, we get 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 221825.63
The remainder is 27 after subtracting 213 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
270 divided by 71 is 3 with a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 221825.633
Deduct 213 from 270 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final outcome is 221825.633, with a leftover of 0.0057.
