42709308 ÷ 669 
We want to divide 42709308 by 669.

Moving on to step 1:
4 divided by 669 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 669

On to step 2:
The number 669 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 669

Advancing to step 3:
The number 669 fits into 427 0 times, leaving a remainder of 427.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 427 to get 427.
Include the next digit (0) from the dividend after 427, then repeat: 4270 / 669

On to step 4:
669 can be fit into 4270 6 times, resulting in a remainder of 256.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 256 after subtracting 4014 from 4270.
Include the next digit (9) from the dividend after 256, then repeat: 2569 / 669

On to step 5:
669 can be fit into 2569 3 times, resulting in a remainder of 562.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Deduct 2007 from 2569 and we're left with 562.
Include the next digit (3) from the dividend after 562, then repeat: 5623 / 669

Advancing to step 6:
669 goes into 5623 8 times with a remainder of 271.
Use 8 as the next digit of our solution. 
Result so far: 638.0
Subtracting 5352 from 5623 leaves us with 271.
Fetch the next digit (0) from the dividend, attach it to 271 and continue: 2710 / 669

Let's proceed to step 7:
2710 divided by 669 is 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 6384.0
If we take 2676 away from 2710, we end up with 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 669

Step 8:
When dividing 348 by 669, we get 0 with a remainder of 348.
Record the quotient 0 as the next digit in the result. 
Result so far: 63840.0
The remainder is 348 after subtracting 0 from 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 9:
669 goes into 3480 5 times with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 63840.5
Subtracting 3345 from 3480 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 10:
669 can be fit into 1350 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 63840.52
Subtracting 1338 from 1350 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
669 can be fit into 120 0 times, resulting in a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 63840.52
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
The number 669 fits into 1200 1 times, leaving a remainder of 531.
Write down 1 as next digit of the result. 
Result so far: 63840.5201
Subtracting 669 from 1200 leaves us with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Advancing to step 13:
669 can be fit into 5310 7 times, resulting in a remainder of 627.
The number 7 becomes the next digit in our result. 
Result so far: 63840.52017
If we take 4683 away from 5310, we end up with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Step 14:
When dividing 6270 by 669, we get 9 with a remainder of 249.
The number 9 becomes the next digit in our result. 
Result so far: 63840.520179
If we subtract 6021 from 6270, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 15:
2490 divided by 669 is 3 with a remainder of 483.
Use 3 as the next digit of our solution. 
Result so far: 63840.5201793
If we subtract 2007 from 2490, we get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Let's proceed to step 16:
669 can be fit into 4830 7 times, resulting in a remainder of 147.
Record the quotient 7 as the next digit in the result. 
Result so far: 63840.52017937
Deduct 4683 from 4830 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

The quotient of the division is 63840.52017937, and the remainder is 1.47e-07.
