Let's divide 85970535 by 668
We're looking to find how many times 668 goes into 85970535.

Advancing to step 1:
8 divided by 668 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 668

Advancing to step 2:
668 goes into 85 0 times with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 668

Advancing to step 3:
668 goes into 859 1 times with a remainder of 191.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 668 from 859, we get 191.
Take the next digit (7) from the dividend and append it to 191, then repeat: 1917 / 668

Going ahead to step 4:
668 can be fit into 1917 2 times, resulting in a remainder of 581.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1336 from 1917 and we're left with 581.
Take the next digit (0) from the dividend and append it to 581, then repeat: 5810 / 668

Going ahead to step 5:
668 can be fit into 5810 8 times, resulting in a remainder of 466.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
If we subtract 5344 from 5810, we get 466.
Grab the next digit (5) from the dividend, add it to 466, then carry on: 4665 / 668

Advancing to step 6:
If we divide 4665 by 668, we get 6 and a remainder of 657.
Use 6 as the next digit of our solution. 
Result so far: 1286.0
If we subtract 4008 from 4665, we get 657.
Bring next digit (3) of the dividend behind the 657 and repeat the process: 6573 / 668

Let's proceed to step 7:
668 goes into 6573 9 times with a remainder of 561.
Write down 9 as next digit of the result. 
Result so far: 12869.0
If we subtract 6012 from 6573, we get 561.
Take the next digit (5) from the dividend and append it to 561, then repeat: 5615 / 668

Moving on to step 8:
668 goes into 5615 8 times with a remainder of 271.
Record the quotient 8 as the next digit in the result. 
Result so far: 128698.0
The remainder is 271 after subtracting 5344 from 5615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Going ahead to step 9:
If we divide 2710 by 668, we get 4 and a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 128698.4
Deduct 2672 from 2710 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
380 divided by 668 is 0 with a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 128698.4
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 11:
If we divide 3800 by 668, we get 5 and a remainder of 460.
The next digit of our result is 5. 
Result so far: 128698.405
Deduct 3340 from 3800 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 12:
4600 divided by 668 is 6 with a remainder of 592.
The number 6 becomes the next digit in our result. 
Result so far: 128698.4056
Deduct 4008 from 4600 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 13:
The number 668 fits into 5920 8 times, leaving a remainder of 576.
Record the quotient 8 as the next digit in the result. 
Result so far: 128698.40568
Subtracting 5344 from 5920 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Step 14:
If we divide 5760 by 668, we get 8 and a remainder of 416.
Record the quotient 8 as the next digit in the result. 
Result so far: 128698.405688
Deduct 5344 from 5760 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

In conclusion, the division gives 128698.405688 with a balance of 4.16e-05.
