We look at the division of 68386174 by 521 
We're looking to find how many times 521 goes into 68386174.

Going ahead to step 1:
521 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 521

Let's proceed to step 2:
521 goes into 68 0 times with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 521

Advancing to step 3:
The number 521 fits into 683 1 times, leaving a remainder of 162.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 521 away from 683, we end up with 162.
Bring next digit (8) of the dividend behind the 162 and repeat the process: 1628 / 521

Moving on to step 4:
1628 divided by 521 is 3 with a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 1563 away from 1628, we end up with 65.
Take the next digit (6) from the dividend and append it to 65, then repeat: 656 / 521

Going ahead to step 5:
When dividing 656 by 521, we get 1 with a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 131.0
Subtracting 521 from 656 leaves us with 135.
Bring next digit (1) of the dividend behind the 135 and repeat the process: 1351 / 521

Let's proceed to step 6:
521 can be fit into 1351 2 times, resulting in a remainder of 309.
Record the quotient 2 as the next digit in the result. 
Result so far: 1312.0
If we subtract 1042 from 1351, we get 309.
Fetch the next digit (7) from the dividend, attach it to 309 and continue: 3097 / 521

Moving on to step 7:
521 can be fit into 3097 5 times, resulting in a remainder of 492.
The number 5 becomes the next digit in our result. 
Result so far: 13125.0
Subtracting 2605 from 3097 leaves us with 492.
Grab the next digit (4) from the dividend, add it to 492, then carry on: 4924 / 521

Advancing to step 8:
When dividing 4924 by 521, we get 9 with a remainder of 235.
Use 9 as the next digit of our solution. 
Result so far: 131259.0
Subtracting 4689 from 4924 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 9:
The number 521 fits into 2350 4 times, leaving a remainder of 266.
The next digit of our result is 4. 
Result so far: 131259.4
Subtracting 2084 from 2350 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 10:
The number 521 fits into 2660 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 131259.45
The remainder is 55 after subtracting 2605 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
When dividing 550 by 521, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 131259.451
Subtracting 521 from 550 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 12:
521 can be fit into 290 0 times, resulting in a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 131259.451
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 13:
2900 divided by 521 is 5 with a remainder of 295.
Use 5 as the next digit of our solution. 
Result so far: 131259.45105
Subtract 2605 from 2900 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 14:
521 goes into 2950 5 times with a remainder of 345.
Record the quotient 5 as the next digit in the result. 
Result so far: 131259.451055
If we take 2605 away from 2950, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Our division results in 131259.451055 with a remaining 3.45e-05.
