We're dividing 90533545 by 149 
Our goal is to divide 90533545 by 149.

Let's proceed to step 1:
When dividing 9 by 149, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 149

On to step 2:
If we divide 90 by 149, we get 0 and a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Append the next digit (5) from the dividend to 90 and continue with: 905 / 149

On to step 3:
When dividing 905 by 149, we get 6 with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 894 away from 905, we end up with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 149

On to step 4:
149 can be fit into 113 0 times, resulting in a remainder of 113.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Subtract 0 from 113 to get 113.
Include the next digit (3) from the dividend after 113, then repeat: 1133 / 149

Moving on to step 5:
1133 divided by 149 is 7 with a remainder of 90.
Use 7 as the next digit of our solution. 
Result so far: 607.0
Deduct 1043 from 1133 and we're left with 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 149

Moving on to step 6:
If we divide 905 by 149, we get 6 and a remainder of 11.
The next digit of our result is 6. 
Result so far: 6076.0
The remainder is 11 after subtracting 894 from 905.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 149

Going ahead to step 7:
The number 149 fits into 114 0 times, leaving a remainder of 114.
The next digit of our result is 0. 
Result so far: 60760.0
Deduct 0 from 114 and we're left with 114.
Append the next digit (5) from the dividend to 114 and continue with: 1145 / 149

Advancing to step 8:
149 goes into 1145 7 times with a remainder of 102.
The next digit of our result is 7. 
Result so far: 607607.0
Deduct 1043 from 1145 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 9:
149 goes into 1020 6 times with a remainder of 126.
The number 6 becomes the next digit in our result. 
Result so far: 607607.6
Deduct 894 from 1020 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 10:
If we divide 1260 by 149, we get 8 and a remainder of 68.
The next digit of our result is 8. 
Result so far: 607607.68
Deduct 1192 from 1260 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 11:
149 can be fit into 680 4 times, resulting in a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 607607.684
Subtract 596 from 680 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
The number 149 fits into 840 5 times, leaving a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 607607.6845
If we subtract 745 from 840, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 13:
149 can be fit into 950 6 times, resulting in a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 607607.68456
If we subtract 894 from 950, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
The number 149 fits into 560 3 times, leaving a remainder of 113.
Write down 3 as next digit of the result. 
Result so far: 607607.684563
Deduct 447 from 560 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 15:
When dividing 1130 by 149, we get 7 with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 607607.6845637
If we take 1043 away from 1130, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 16:
149 goes into 870 5 times with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 607607.68456375
If we subtract 745 from 870, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The final outcome is 607607.68456375, with a leftover of 1.25e-07.
