We divide 77879160 by 669
We want to figure out the number of times 77879160 can be divided by 669.

Let's proceed to step 1:
669 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 669

Let's proceed to step 2:
77 divided by 669 is 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 669

On to step 3:
778 divided by 669 is 1 with a remainder of 109.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 669 away from 778, we end up with 109.
Bring next digit (7) of the dividend behind the 109 and repeat the process: 1097 / 669

Moving on to step 4:
When dividing 1097 by 669, we get 1 with a remainder of 428.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 669 from 1097 leaves us with 428.
Grab the next digit (9) from the dividend, add it to 428, then carry on: 4289 / 669

Going ahead to step 5:
The number 669 fits into 4289 6 times, leaving a remainder of 275.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
If we take 4014 away from 4289, we end up with 275.
Include the next digit (1) from the dividend after 275, then repeat: 2751 / 669

Let's proceed to step 6:
The number 669 fits into 2751 4 times, leaving a remainder of 75.
Record the quotient 4 as the next digit in the result. 
Result so far: 1164.0
Subtract 2676 from 2751 to get 75.
Fetch the next digit (6) from the dividend, attach it to 75 and continue: 756 / 669

On to step 7:
669 can be fit into 756 1 times, resulting in a remainder of 87.
Write down 1 as next digit of the result. 
Result so far: 11641.0
If we subtract 669 from 756, we get 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 669

Let's proceed to step 8:
If we divide 870 by 669, we get 1 and a remainder of 201.
Put 1 as the next digit of the answer. 
Result so far: 116411.0
Subtracting 669 from 870 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 9:
The number 669 fits into 2010 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 116411.3
Subtract 2007 from 2010 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
When dividing 30 by 669, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 116411.3
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
669 can be fit into 300 0 times, resulting in a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 116411.3
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 116411.3, and the remainder is 0.03.
