Let's divide 83986462 by 520
We want to figure out the number of times 83986462 can be divided by 520.

Going ahead to step 1:
520 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 520

Let's proceed to step 2:
The number 520 fits into 83 0 times, leaving a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 520

Moving on to step 3:
520 goes into 839 1 times with a remainder of 319.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 520 from 839 to get 319.
Grab the next digit (8) from the dividend, add it to 319, then carry on: 3198 / 520

Advancing to step 4:
If we divide 3198 by 520, we get 6 and a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 3120 from 3198 leaves us with 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 520

Moving on to step 5:
If we divide 786 by 520, we get 1 and a remainder of 266.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
The remainder is 266 after subtracting 520 from 786.
Fetch the next digit (4) from the dividend, attach it to 266 and continue: 2664 / 520

On to step 6:
2664 divided by 520 is 5 with a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 1615.0
If we take 2600 away from 2664, we end up with 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 520

Let's proceed to step 7:
520 can be fit into 646 1 times, resulting in a remainder of 126.
The next digit of our result is 1. 
Result so far: 16151.0
If we take 520 away from 646, we end up with 126.
Include the next digit (2) from the dividend after 126, then repeat: 1262 / 520

Step 8:
If we divide 1262 by 520, we get 2 and a remainder of 222.
Put 2 as the next digit of the answer. 
Result so far: 161512.0
If we take 1040 away from 1262, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 9:
If we divide 2220 by 520, we get 4 and a remainder of 140.
The next digit of our result is 4. 
Result so far: 161512.4
The remainder is 140 after subtracting 2080 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
The number 520 fits into 1400 2 times, leaving a remainder of 360.
Record the quotient 2 as the next digit in the result. 
Result so far: 161512.42
Subtracting 1040 from 1400 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
When dividing 3600 by 520, we get 6 with a remainder of 480.
Use 6 as the next digit of our solution. 
Result so far: 161512.426
Deduct 3120 from 3600 and we're left 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 12:
The number 520 fits into 4800 9 times, leaving a remainder of 120.
The number 9 becomes the next digit in our result. 
Result so far: 161512.4269
If we subtract 4680 from 4800, we 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.

Going ahead to step 13:
520 goes into 1200 2 times with a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 161512.42692
If we take 1040 away from 1200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
When dividing 1600 by 520, we get 3 with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 161512.426923
Subtract 1560 from 1600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
The number 520 fits into 400 0 times, leaving a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 161512.426923
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 16:
The number 520 fits into 4000 7 times, leaving a remainder of 360.
Put 7 as the next digit of the answer. 
Result so far: 161512.42692307
The remainder is 360 after subtracting 3640 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Our division results in 161512.42692307 with a remaining 3.6e-07.
