90042178 ÷ 536 
We want to figure out the number of times 90042178 can be divided by 536.

On to step 1:
If we divide 9 by 536, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 536

Moving on to step 2:
If we divide 90 by 536, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Append the next digit (0) from the dividend to 90 and continue with: 900 / 536

Step 3:
536 can be fit into 900 1 times, resulting in a remainder of 364.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 536 from 900 to get 364.
Fetch the next digit (4) from the dividend, attach it to 364 and continue: 3644 / 536

Step 4:
536 goes into 3644 6 times with a remainder of 428.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 3216 from 3644 and we're left with 428.
Grab the next digit (2) from the dividend, add it to 428, then carry on: 4282 / 536

On to step 5:
When dividing 4282 by 536, we get 7 with a remainder of 530.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
Subtract 3752 from 4282 to get 530.
Take the next digit (1) from the dividend and append it to 530, then repeat: 5301 / 536

On to step 6:
536 goes into 5301 9 times with a remainder of 477.
The number 9 becomes the next digit in our result. 
Result so far: 1679.0
Deduct 4824 from 5301 and we're left with 477.
Grab the next digit (7) from the dividend, add it to 477, then carry on: 4777 / 536

Let's proceed to step 7:
If we divide 4777 by 536, we get 8 and a remainder of 489.
Put 8 as the next digit of the answer. 
Result so far: 16798.0
If we subtract 4288 from 4777, we get 489.
Fetch the next digit (8) from the dividend, attach it to 489 and continue: 4898 / 536

Going ahead to step 8:
4898 divided by 536 is 9 with a remainder of 74.
Record the quotient 9 as the next digit in the result. 
Result so far: 167989.0
If we subtract 4824 from 4898, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 9:
If we divide 740 by 536, we get 1 and a remainder of 204.
The number 1 becomes the next digit in our result. 
Result so far: 167989.1
Subtracting 536 from 740 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 10:
536 can be fit into 2040 3 times, resulting in a remainder of 432.
Record the quotient 3 as the next digit in the result. 
Result so far: 167989.13
Deduct 1608 from 2040 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 11:
When dividing 4320 by 536, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 167989.138
The remainder is 32 after subtracting 4288 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
When dividing 320 by 536, we get 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 167989.138
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 13:
536 can be fit into 3200 5 times, resulting in a remainder of 520.
Put 5 as the next digit of the answer. 
Result so far: 167989.13805
Deduct 2680 from 3200 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 14:
The number 536 fits into 5200 9 times, leaving a remainder of 376.
Use 9 as the next digit of our solution. 
Result so far: 167989.138059
Subtracting 4824 from 5200 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 15:
If we divide 3760 by 536, we get 7 and a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 167989.1380597
The remainder is 8 after subtracting 3752 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 16:
80 divided by 536 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 167989.1380597
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 167989.1380597 with a remainder of 8e-08.
