90870988 ÷ 154 
Let's see how many times 154 fits into 90870988.

Step 1:
154 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 154

On to step 2:
When dividing 90 by 154, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Take the next digit (8) from the dividend and append it to 90, then repeat: 908 / 154

Moving on to step 3:
154 can be fit into 908 5 times, resulting in a remainder of 138.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 770 from 908 to get 138.
Fetch the next digit (7) from the dividend, attach it to 138 and continue: 1387 / 154

On to step 4:
If we divide 1387 by 154, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Deduct 1386 from 1387 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 154

On to step 5:
If we divide 10 by 154, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 590.0
Deduct 0 from 10 and we're left with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 154

Advancing to step 6:
154 goes into 109 0 times with a remainder of 109.
The number 0 becomes the next digit in our result. 
Result so far: 5900.0
If we take 0 away from 109, we end up with 109.
Bring next digit (8) of the dividend behind the 109 and repeat the process: 1098 / 154

Moving on to step 7:
If we divide 1098 by 154, we get 7 and a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 59007.0
The remainder is 20 after subtracting 1078 from 1098.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 154

Moving on to step 8:
When dividing 208 by 154, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 590071.0
If we take 154 away from 208, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
540 divided by 154 is 3 with a remainder of 78.
Put 3 as the next digit of the answer. 
Result so far: 590071.3
Deduct 462 from 540 and we're left 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.

Step 10:
If we divide 780 by 154, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 590071.35
The remainder is 10 after subtracting 770 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
154 goes into 100 0 times with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 590071.35
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 12:
The number 154 fits into 1000 6 times, leaving a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 590071.3506
Subtracting 924 from 1000 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 13:
When dividing 760 by 154, we get 4 with a remainder of 144.
Write down 4 as next digit of the result. 
Result so far: 590071.35064
Subtracting 616 from 760 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 14:
If we divide 1440 by 154, we get 9 and a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 590071.350649
Deduct 1386 from 1440 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 15:
540 divided by 154 is 3 with a remainder of 78.
Put 3 as the next digit of the answer. 
Result so far: 590071.3506493
If we take 462 away from 540, we end up 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.

Advancing to step 16:
The number 154 fits into 780 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 590071.35064935
Subtracting 770 from 780 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 590071.35064935 with a balance of 1e-08.
