86938092 ÷ 858 
We're looking to find how many times 858 goes into 86938092.

Going ahead to step 1:
If we divide 8 by 858, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 858

Going ahead to step 2:
86 divided by 858 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 858

Let's proceed to step 3:
869 divided by 858 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 858 from 869 to get 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 858

Advancing to step 4:
113 divided by 858 is 0 with a remainder of 113.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 113, we end up with 113.
Grab the next digit (8) from the dividend, add it to 113, then carry on: 1138 / 858

Moving on to step 5:
The number 858 fits into 1138 1 times, leaving a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtracting 858 from 1138 leaves us with 280.
Grab the next digit (0) from the dividend, add it to 280, then carry on: 2800 / 858

On to step 6:
858 can be fit into 2800 3 times, resulting in a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 1013.0
If we subtract 2574 from 2800, we get 226.
Take the next digit (9) from the dividend and append it to 226, then repeat: 2269 / 858

Advancing to step 7:
The number 858 fits into 2269 2 times, leaving a remainder of 553.
Record the quotient 2 as the next digit in the result. 
Result so far: 10132.0
If we take 1716 away from 2269, we end up with 553.
Bring next digit (2) of the dividend behind the 553 and repeat the process: 5532 / 858

On to step 8:
858 can be fit into 5532 6 times, resulting in a remainder of 384.
Use 6 as the next digit of our solution. 
Result so far: 101326.0
Subtracting 5148 from 5532 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 9:
If we divide 3840 by 858, we get 4 and a remainder of 408.
Put 4 as the next digit of the answer. 
Result so far: 101326.4
Subtract 3432 from 3840 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 10:
When dividing 4080 by 858, we get 4 with a remainder of 648.
Record the quotient 4 as the next digit in the result. 
Result so far: 101326.44
If we take 3432 away from 4080, we end up with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

After the division, we end up with 101326.44 and a remainder of 0.648.
