85890801 ÷ 138 
We want to figure out the number of times 85890801 can be divided by 138.

Going ahead to step 1:
138 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 138

Let's proceed to step 2:
If we divide 85 by 138, we get 0 and a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Include the next digit (8) from the dividend after 85, then repeat: 858 / 138

Going ahead to step 3:
The number 138 fits into 858 6 times, leaving a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 30 after subtracting 828 from 858.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 138

Step 4:
309 divided by 138 is 2 with a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 62.0
The remainder is 33 after subtracting 276 from 309.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 138

Moving on to step 5:
138 can be fit into 330 2 times, resulting in a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 622.0
Subtracting 276 from 330 leaves us with 54.
Fetch the next digit (8) from the dividend, attach it to 54 and continue: 548 / 138

Going ahead to step 6:
If we divide 548 by 138, we get 3 and a remainder of 134.
Put 3 as the next digit of the answer. 
Result so far: 6223.0
Subtracting 414 from 548 leaves us with 134.
Grab the next digit (0) from the dividend, add it to 134, then carry on: 1340 / 138

Step 7:
If we divide 1340 by 138, we get 9 and a remainder of 98.
The next digit of our result is 9. 
Result so far: 62239.0
Subtracting 1242 from 1340 leaves us with 98.
Include the next digit (1) from the dividend after 98, then repeat: 981 / 138

Moving on to step 8:
If we divide 981 by 138, we get 7 and a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 622397.0
If we subtract 966 from 981, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
138 can be fit into 150 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 622397.1
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
138 can be fit into 120 0 times, resulting in a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 622397.1
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
The number 138 fits into 1200 8 times, leaving a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 622397.108
The remainder is 96 after subtracting 1104 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 12:
If we divide 960 by 138, we get 6 and a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 622397.1086
Deduct 828 from 960 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 13:
138 can be fit into 1320 9 times, resulting in a remainder of 78.
The next digit of our result is 9. 
Result so far: 622397.10869
Subtracting 1242 from 1320 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 14:
The number 138 fits into 780 5 times, leaving a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 622397.108695
Subtract 690 from 780 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 15:
When dividing 900 by 138, we get 6 with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 622397.1086956
Subtracting 828 from 900 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 16:
If we divide 720 by 138, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 622397.10869565
If we take 690 away from 720, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 622397.10869565, with a leftover of 3e-08.
