We're dividing 379521 by 85 
We want to figure out the number of times 379521 can be divided by 85.

Advancing to step 1:
85 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 85

Advancing to step 2:
When dividing 37 by 85, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 85

On to step 3:
85 goes into 379 4 times with a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 340 from 379 and we're left with 39.
Bring next digit (5) of the dividend behind the 39 and repeat the process: 395 / 85

Step 4:
The number 85 fits into 395 4 times, leaving a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 44.0
The remainder is 55 after subtracting 340 from 395.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 85

Going ahead to step 5:
If we divide 552 by 85, we get 6 and a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 446.0
Subtract 510 from 552 to get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 85

On to step 6:
When dividing 421 by 85, we get 4 with a remainder of 81.
The number 4 becomes the next digit in our result. 
Result so far: 4464.0
Subtracting 340 from 421 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 7:
When dividing 810 by 85, we get 9 with a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 4464.9
Deduct 765 from 810 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
85 goes into 450 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4464.95
Deduct 425 from 450 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
When dividing 250 by 85, we get 2 with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 4464.952
Deduct 170 from 250 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
The number 85 fits into 800 9 times, leaving a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 4464.9529
Deduct 765 from 800 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
The number 85 fits into 350 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 4464.95294
Deduct 340 from 350 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
If we divide 100 by 85, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 4464.952941
If we subtract 85 from 100, we get 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 13:
85 goes into 150 1 times with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 4464.9529411
Subtracting 85 from 150 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 4464.9529411 and a remainder of 6.5e-07.
