Let's divide 352521 by 77
Let's see how many times 77 fits into 352521.

Moving on to step 1:
77 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 77

Moving on to step 2:
77 goes into 35 0 times with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 77

Step 3:
77 can be fit into 352 4 times, resulting in a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 308 from 352 to get 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 77

Let's proceed to step 4:
77 can be fit into 445 5 times, resulting in a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 385 from 445 to get 60.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 77

Let's proceed to step 5:
77 goes into 602 7 times with a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 457.0
Deduct 539 from 602 and we're left with 63.
Include the next digit (1) from the dividend after 63, then repeat: 631 / 77

Let's proceed to step 6:
If we divide 631 by 77, we get 8 and a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 4578.0
Subtracting 616 from 631 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
If we divide 150 by 77, we get 1 and a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 4578.1
If we take 77 away from 150, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 8:
77 goes into 730 9 times with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 4578.19
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
The number 77 fits into 370 4 times, leaving a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 4578.194
Deduct 308 from 370 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
77 goes into 620 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 4578.1948
Deduct 616 from 620 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
If we divide 40 by 77, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 4578.1948
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
77 can be fit into 400 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 4578.194805
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
77 can be fit into 150 1 times, resulting in a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 4578.1948051
Subtract 77 from 150 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 14:
If we divide 730 by 77, we get 9 and a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 4578.19480519
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The quotient of the division is 4578.19480519, and the remainder is 3.7e-08.
