We look at the division of 93121964 by 858 
Let's see how many times 858 fits into 93121964.

Going ahead to step 1:
When dividing 9 by 858, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 858

Advancing to step 2:
When dividing 93 by 858, we get 0 with a remainder of 93.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 93 to get 93.
Append the next digit (1) from the dividend to 93 and continue with: 931 / 858

Advancing to step 3:
858 goes into 931 1 times with a remainder of 73.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 858 from 931 and we're left with 73.
Include the next digit (2) from the dividend after 73, then repeat: 732 / 858

On to step 4:
The number 858 fits into 732 0 times, leaving a remainder of 732.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 732, we get 732.
Fetch the next digit (1) from the dividend, attach it to 732 and continue: 7321 / 858

Let's proceed to step 5:
If we divide 7321 by 858, we get 8 and a remainder of 457.
The next digit of our result is 8. 
Result so far: 108.0
Subtract 6864 from 7321 to get 457.
Bring next digit (9) of the dividend behind the 457 and repeat the process: 4579 / 858

Moving on to step 6:
When dividing 4579 by 858, we get 5 with a remainder of 289.
The next digit of our result is 5. 
Result so far: 1085.0
Deduct 4290 from 4579 and we're left with 289.
Grab the next digit (6) from the dividend, add it to 289, then carry on: 2896 / 858

On to step 7:
The number 858 fits into 2896 3 times, leaving a remainder of 322.
The number 3 becomes the next digit in our result. 
Result so far: 10853.0
Subtract 2574 from 2896 to get 322.
Append the next digit (4) from the dividend to 322 and continue with: 3224 / 858

On to step 8:
If we divide 3224 by 858, we get 3 and a remainder of 650.
Record the quotient 3 as the next digit in the result. 
Result so far: 108533.0
If we subtract 2574 from 3224, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 9:
If we divide 6500 by 858, we get 7 and a remainder of 494.
Put 7 as the next digit of the answer. 
Result so far: 108533.7
The remainder is 494 after subtracting 6006 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Step 10:
If we divide 4940 by 858, we get 5 and a remainder of 650.
Put 5 as the next digit of the answer. 
Result so far: 108533.75
Deduct 4290 from 4940 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 11:
858 goes into 6500 7 times with a remainder of 494.
The number 7 becomes the next digit in our result. 
Result so far: 108533.757
If we take 6006 away from 6500, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Let's proceed to step 12:
If we divide 4940 by 858, we get 5 and a remainder of 650.
Use 5 as the next digit of our solution. 
Result so far: 108533.7575
If we subtract 4290 from 4940, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 13:
The number 858 fits into 6500 7 times, leaving a remainder of 494.
The next digit of our result is 7. 
Result so far: 108533.75757
Subtract 6006 from 6500 to get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 14:
If we divide 4940 by 858, we get 5 and a remainder of 650.
Record the quotient 5 as the next digit in the result. 
Result so far: 108533.757575
The remainder is 650 after subtracting 4290 from 4940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 15:
The number 858 fits into 6500 7 times, leaving a remainder of 494.
The next digit of our result is 7. 
Result so far: 108533.7575757
If we take 6006 away from 6500, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 16:
When dividing 4940 by 858, we get 5 with a remainder of 650.
The number 5 becomes the next digit in our result. 
Result so far: 108533.75757575
The remainder is 650 after subtracting 4290 from 4940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

In conclusion, the division gives 108533.75757575 with a balance of 6.5e-07.
