86889937 ÷ 920 
We want to figure out the number of times 86889937 can be divided by 920.

Step 1:
The number 920 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 920

Advancing to step 2:
The number 920 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 920

Step 3:
868 divided by 920 is 0 with a remainder of 868.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 868 leaves us with 868.
Grab the next digit (8) from the dividend, add it to 868, then carry on: 8688 / 920

Step 4:
920 goes into 8688 9 times with a remainder of 408.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 8280 from 8688, we get 408.
Include the next digit (9) from the dividend after 408, then repeat: 4089 / 920

On to step 5:
920 goes into 4089 4 times with a remainder of 409.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Subtracting 3680 from 4089 leaves us with 409.
Fetch the next digit (9) from the dividend, attach it to 409 and continue: 4099 / 920

Advancing to step 6:
When dividing 4099 by 920, we get 4 with a remainder of 419.
Use 4 as the next digit of our solution. 
Result so far: 944.0
Deduct 3680 from 4099 and we're left with 419.
Fetch the next digit (3) from the dividend, attach it to 419 and continue: 4193 / 920

Step 7:
4193 divided by 920 is 4 with a remainder of 513.
Put 4 as the next digit of the answer. 
Result so far: 9444.0
Deduct 3680 from 4193 and we're left with 513.
Grab the next digit (7) from the dividend, add it to 513, then carry on: 5137 / 920

Step 8:
920 can be fit into 5137 5 times, resulting in a remainder of 537.
The next digit of our result is 5. 
Result so far: 94445.0
The remainder is 537 after subtracting 4600 from 5137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Advancing to step 9:
920 can be fit into 5370 5 times, resulting in a remainder of 770.
The next digit of our result is 5. 
Result so far: 94445.5
The remainder is 770 after subtracting 4600 from 5370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Let's proceed to step 10:
When dividing 7700 by 920, we get 8 with a remainder of 340.
Use 8 as the next digit of our solution. 
Result so far: 94445.58
Subtracting 7360 from 7700 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 11:
The number 920 fits into 3400 3 times, leaving a remainder of 640.
Use 3 as the next digit of our solution. 
Result so far: 94445.583
If we take 2760 away from 3400, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 12:
When dividing 6400 by 920, we get 6 with a remainder of 880.
Put 6 as the next digit of the answer. 
Result so far: 94445.5836
If we take 5520 away from 6400, we end up with 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Moving on to step 13:
If we divide 8800 by 920, we get 9 and a remainder of 520.
Record the quotient 9 as the next digit in the result. 
Result so far: 94445.58369
If we subtract 8280 from 8800, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 14:
920 can be fit into 5200 5 times, resulting in a remainder of 600.
The next digit of our result is 5. 
Result so far: 94445.583695
Subtracting 4600 from 5200 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 15:
920 goes into 6000 6 times with a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 94445.5836956
The remainder is 480 after subtracting 5520 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 16:
The number 920 fits into 4800 5 times, leaving a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 94445.58369565
The remainder is 200 after subtracting 4600 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 94445.58369565 and a remainder of 2e-07.
