We look at the division of 71521992 by 669 
We're looking to find how many times 669 goes into 71521992.

Moving on to step 1:
When dividing 7 by 669, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 669

Let's proceed to step 2:
669 goes into 71 0 times with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Append the next digit (5) from the dividend to 71 and continue with: 715 / 669

Advancing to step 3:
If we divide 715 by 669, we get 1 and a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 669 from 715 and we're left with 46.
Grab the next digit (2) from the dividend, add it to 46, then carry on: 462 / 669

Going ahead to step 4:
669 goes into 462 0 times with a remainder of 462.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 462 after subtracting 0 from 462.
Grab the next digit (1) from the dividend, add it to 462, then carry on: 4621 / 669

Step 5:
When dividing 4621 by 669, we get 6 with a remainder of 607.
Use 6 as the next digit of our solution. 
Result so far: 106.0
The remainder is 607 after subtracting 4014 from 4621.
Bring next digit (9) of the dividend behind the 607 and repeat the process: 6079 / 669

Advancing to step 6:
When dividing 6079 by 669, we get 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 1069.0
Subtracting 6021 from 6079 leaves us with 58.
Fetch the next digit (9) from the dividend, attach it to 58 and continue: 589 / 669

Moving on to step 7:
589 divided by 669 is 0 with a remainder of 589.
Put 0 as the next digit of the answer. 
Result so far: 10690.0
Subtracting 0 from 589 leaves us with 589.
Bring next digit (2) of the dividend behind the 589 and repeat the process: 5892 / 669

Moving on to step 8:
The number 669 fits into 5892 8 times, leaving a remainder of 540.
Put 8 as the next digit of the answer. 
Result so far: 106908.0
If we take 5352 away from 5892, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 9:
When dividing 5400 by 669, we get 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 106908.8
Subtracting 5352 from 5400 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
669 can be fit into 480 0 times, resulting in a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 106908.8
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 11:
When dividing 4800 by 669, we get 7 with a remainder of 117.
Write down 7 as next digit of the result. 
Result so far: 106908.807
Subtracting 4683 from 4800 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 12:
When dividing 1170 by 669, we get 1 with a remainder of 501.
Record the quotient 1 as the next digit in the result. 
Result so far: 106908.8071
If we take 669 away from 1170, we end up with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Let's proceed to step 13:
When dividing 5010 by 669, we get 7 with a remainder of 327.
Use 7 as the next digit of our solution. 
Result so far: 106908.80717
Subtract 4683 from 5010 to get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Let's proceed to step 14:
If we divide 3270 by 669, we get 4 and a remainder of 594.
The next digit of our result is 4. 
Result so far: 106908.807174
If we subtract 2676 from 3270, we get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Step 15:
The number 669 fits into 5940 8 times, leaving a remainder of 588.
Write down 8 as next digit of the result. 
Result so far: 106908.8071748
Deduct 5352 from 5940 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.

Advancing to step 16:
669 can be fit into 5880 8 times, resulting in a remainder of 528.
Record the quotient 8 as the next digit in the result. 
Result so far: 106908.80717488
The remainder is 528 after subtracting 5352 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

The quotient of the division is 106908.80717488, and the remainder is 5.28e-07.
