We look at the division of 30689138 by 155 
We want to figure out the number of times 30689138 can be divided by 155.

Going ahead to step 1:
155 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 155

Let's proceed to step 2:
The number 155 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 155

Step 3:
When dividing 306 by 155, we get 1 with a remainder of 151.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 151 after subtracting 155 from 306.
Append the next digit (8) from the dividend to 151 and continue with: 1518 / 155

Step 4:
The number 155 fits into 1518 9 times, leaving a remainder of 123.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 1395 from 1518 leaves us with 123.
Bring next digit (9) of the dividend behind the 123 and repeat the process: 1239 / 155

Going ahead to step 5:
155 goes into 1239 7 times with a remainder of 154.
Put 7 as the next digit of the answer. 
Result so far: 197.0
Deduct 1085 from 1239 and we're left with 154.
Grab the next digit (1) from the dividend, add it to 154, then carry on: 1541 / 155

Let's proceed to step 6:
If we divide 1541 by 155, we get 9 and a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 1979.0
Deduct 1395 from 1541 and we're left with 146.
Take the next digit (3) from the dividend and append it to 146, then repeat: 1463 / 155

On to step 7:
155 goes into 1463 9 times with a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 19799.0
Deduct 1395 from 1463 and we're left with 68.
Append the next digit (8) from the dividend to 68 and continue with: 688 / 155

On to step 8:
688 divided by 155 is 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 197994.0
Deduct 620 from 688 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.

Step 9:
680 divided by 155 is 4 with a remainder of 60.
The next digit of our result is 4. 
Result so far: 197994.4
Subtract 620 from 680 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
155 goes into 600 3 times with a remainder of 135.
The number 3 becomes the next digit in our result. 
Result so far: 197994.43
Subtracting 465 from 600 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 11:
155 goes into 1350 8 times with a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 197994.438
Subtracting 1240 from 1350 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 12:
When dividing 1100 by 155, we get 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 197994.4387
Subtracting 1085 from 1100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
The number 155 fits into 150 0 times, leaving a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 197994.4387
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 14:
155 can be fit into 1500 9 times, resulting in a remainder of 105.
The number 9 becomes the next digit in our result. 
Result so far: 197994.438709
Subtract 1395 from 1500 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 15:
The number 155 fits into 1050 6 times, leaving a remainder of 120.
The next digit of our result is 6. 
Result so far: 197994.4387096
Subtracting 930 from 1050 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 16:
1200 divided by 155 is 7 with a remainder of 115.
Use 7 as the next digit of our solution. 
Result so far: 197994.43870967
The remainder is 115 after subtracting 1085 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The quotient of the division is 197994.43870967, and the remainder is 1.15e-07.
