We're dividing 84403158 by 156 
Let's see how many times 156 fits into 84403158.

Going ahead to step 1:
156 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 156

Advancing to step 2:
156 goes into 84 0 times with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Bring next digit (4) of the dividend behind the 84 and repeat the process: 844 / 156

On to step 3:
If we divide 844 by 156, we get 5 and a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 780 away from 844, we end up with 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 156

Step 4:
When dividing 640 by 156, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we subtract 624 from 640, we get 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 156

Let's proceed to step 5:
156 goes into 163 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 541.0
Subtracting 156 from 163 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 156

Advancing to step 6:
If we divide 71 by 156, we get 0 and a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 5410.0
Subtracting 0 from 71 leaves us with 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 156

Advancing to step 7:
If we divide 715 by 156, we get 4 and a remainder of 91.
Write down 4 as next digit of the result. 
Result so far: 54104.0
Subtracting 624 from 715 leaves us with 91.
Bring next digit (8) of the dividend behind the 91 and repeat the process: 918 / 156

On to step 8:
The number 156 fits into 918 5 times, leaving a remainder of 138.
Put 5 as the next digit of the answer. 
Result so far: 541045.0
Subtracting 780 from 918 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 9:
The number 156 fits into 1380 8 times, leaving a remainder of 132.
Write down 8 as next digit of the result. 
Result so far: 541045.8
The remainder is 132 after subtracting 1248 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 10:
156 goes into 1320 8 times with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 541045.88
Deduct 1248 from 1320 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 541045.88 with a remaining 0.072.
