We're dividing 7138621 by 151 
Let's see how many times 151 fits into 7138621.

Step 1:
7 divided by 151 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 151

Step 2:
151 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 151

Going ahead to step 3:
The number 151 fits into 713 4 times, leaving a remainder of 109.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 604 from 713 to get 109.
Append the next digit (8) from the dividend to 109 and continue with: 1098 / 151

Going ahead to step 4:
If we divide 1098 by 151, we get 7 and a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 47.0
The remainder is 41 after subtracting 1057 from 1098.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 151

Moving on to step 5:
When dividing 416 by 151, we get 2 with a remainder of 114.
Write down 2 as next digit of the result. 
Result so far: 472.0
Subtracting 302 from 416 leaves us with 114.
Include the next digit (2) from the dividend after 114, then repeat: 1142 / 151

Going ahead to step 6:
151 goes into 1142 7 times with a remainder of 85.
The number 7 becomes the next digit in our result. 
Result so far: 4727.0
The remainder is 85 after subtracting 1057 from 1142.
Take the next digit (1) from the dividend and append it to 85, then repeat: 851 / 151

Step 7:
The number 151 fits into 851 5 times, leaving a remainder of 96.
Write down 5 as next digit of the result. 
Result so far: 47275.0
If we take 755 away from 851, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 8:
960 divided by 151 is 6 with a remainder of 54.
The next digit of our result is 6. 
Result so far: 47275.6
The remainder is 54 after subtracting 906 from 960.
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:
When dividing 540 by 151, we get 3 with a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 47275.63
If we take 453 away from 540, 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 10:
151 goes into 870 5 times with a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 47275.635
Deduct 755 from 870 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 11:
151 goes into 1150 7 times with a remainder of 93.
The number 7 becomes the next digit in our result. 
Result so far: 47275.6357
If we subtract 1057 from 1150, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 12:
151 can be fit into 930 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 47275.63576
Deduct 906 from 930 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
151 can be fit into 240 1 times, resulting in a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 47275.635761
Subtract 151 from 240 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 14:
The number 151 fits into 890 5 times, leaving a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 47275.6357615
Subtract 755 from 890 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 15:
When dividing 1350 by 151, we get 8 with a remainder of 142.
The number 8 becomes the next digit in our result. 
Result so far: 47275.63576158
If we subtract 1208 from 1350, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The final outcome is 47275.63576158, with a leftover of 1.42e-07.
