We're dividing 71971051 by 664 
We want to divide 71971051 by 664.

Advancing to step 1:
664 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 664

Step 2:
664 can be fit into 71 0 times, resulting in a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 664

Moving on to step 3:
664 can be fit into 719 1 times, resulting in a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 664 from 719 leaves us with 55.
Grab the next digit (7) from the dividend, add it to 55, then carry on: 557 / 664

Let's proceed to step 4:
557 divided by 664 is 0 with a remainder of 557.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 557, we get 557.
Fetch the next digit (1) from the dividend, attach it to 557 and continue: 5571 / 664

Going ahead to step 5:
5571 divided by 664 is 8 with a remainder of 259.
The next digit of our result is 8. 
Result so far: 108.0
The remainder is 259 after subtracting 5312 from 5571.
Take the next digit (0) from the dividend and append it to 259, then repeat: 2590 / 664

Let's proceed to step 6:
664 goes into 2590 3 times with a remainder of 598.
Put 3 as the next digit of the answer. 
Result so far: 1083.0
The remainder is 598 after subtracting 1992 from 2590.
Append the next digit (5) from the dividend to 598 and continue with: 5985 / 664

Step 7:
664 goes into 5985 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 10839.0
If we take 5976 away from 5985, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 664

Advancing to step 8:
664 goes into 91 0 times with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 108390.0
The remainder is 91 after subtracting 0 from 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 9:
If we divide 910 by 664, we get 1 and a remainder of 246.
Write down 1 as next digit of the result. 
Result so far: 108390.1
Deduct 664 from 910 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 10:
When dividing 2460 by 664, we get 3 with a remainder of 468.
Record the quotient 3 as the next digit in the result. 
Result so far: 108390.13
Subtracting 1992 from 2460 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 11:
When dividing 4680 by 664, we get 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 108390.137
If we subtract 4648 from 4680, 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.

Moving on to step 12:
664 can be fit into 320 0 times, resulting in a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 108390.137
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 13:
The number 664 fits into 3200 4 times, leaving a remainder of 544.
Record the quotient 4 as the next digit in the result. 
Result so far: 108390.13704
If we subtract 2656 from 3200, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 14:
664 goes into 5440 8 times with a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 108390.137048
Subtracting 5312 from 5440 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 15:
When dividing 1280 by 664, we get 1 with a remainder of 616.
The next digit of our result is 1. 
Result so far: 108390.1370481
The remainder is 616 after subtracting 664 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Going ahead to step 16:
If we divide 6160 by 664, we get 9 and a remainder of 184.
Put 9 as the next digit of the answer. 
Result so far: 108390.13704819
If we take 5976 away from 6160, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final outcome is 108390.13704819, with a leftover of 1.84e-07.
