We're dividing 3400769 by 151 
We want to divide 3400769 by 151.

Let's proceed to step 1:
If we divide 3 by 151, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 151

Moving on to step 2:
If we divide 34 by 151, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 151

Step 3:
151 can be fit into 340 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 302 from 340 and we're left with 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 151

Going ahead to step 4:
151 can be fit into 380 2 times, resulting in a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtracting 302 from 380 leaves us with 78.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 151

Advancing to step 5:
151 goes into 787 5 times with a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 225.0
Deduct 755 from 787 and we're left with 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 151

Step 6:
When dividing 326 by 151, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 2252.0
Deduct 302 from 326 and we're left with 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 151

Going ahead to step 7:
The number 151 fits into 249 1 times, leaving a remainder of 98.
The next digit of our result is 1. 
Result so far: 22521.0
Subtract 151 from 249 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 8:
If we divide 980 by 151, we get 6 and a remainder of 74.
The next digit of our result is 6. 
Result so far: 22521.6
Subtracting 906 from 980 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 9:
151 goes into 740 4 times with a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 22521.64
Subtract 604 from 740 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 10:
When dividing 1360 by 151, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 22521.649
Subtracting 1359 from 1360 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
151 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 22521.649
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
151 goes into 100 0 times with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 22521.649
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 22521.649 with a remainder of 0.0001.
