We're dividing 21551258 by 942 
Our goal is to divide 21551258 by 942.

Moving on to step 1:
942 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 942

Advancing to step 2:
When dividing 21 by 942, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 942

On to step 3:
If we divide 215 by 942, we get 0 and a remainder of 215.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 215 leaves us with 215.
Append the next digit (5) from the dividend to 215 and continue with: 2155 / 942

Let's proceed to step 4:
When dividing 2155 by 942, we get 2 with a remainder of 271.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 271 after subtracting 1884 from 2155.
Include the next digit (1) from the dividend after 271, then repeat: 2711 / 942

Advancing to step 5:
If we divide 2711 by 942, we get 2 and a remainder of 827.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtracting 1884 from 2711 leaves us with 827.
Include the next digit (2) from the dividend after 827, then repeat: 8272 / 942

Advancing to step 6:
The number 942 fits into 8272 8 times, leaving a remainder of 736.
Use 8 as the next digit of our solution. 
Result so far: 228.0
The remainder is 736 after subtracting 7536 from 8272.
Append the next digit (5) from the dividend to 736 and continue with: 7365 / 942

Going ahead to step 7:
The number 942 fits into 7365 7 times, leaving a remainder of 771.
Write down 7 as next digit of the result. 
Result so far: 2287.0
Subtracting 6594 from 7365 leaves us with 771.
Fetch the next digit (8) from the dividend, attach it to 771 and continue: 7718 / 942

Advancing to step 8:
7718 divided by 942 is 8 with a remainder of 182.
The next digit of our result is 8. 
Result so far: 22878.0
Deduct 7536 from 7718 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 9:
1820 divided by 942 is 1 with a remainder of 878.
The number 1 becomes the next digit in our result. 
Result so far: 22878.1
Deduct 942 from 1820 and we're left with 878.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8780, and continue the process.

Advancing to step 10:
942 goes into 8780 9 times with a remainder of 302.
Put 9 as the next digit of the answer. 
Result so far: 22878.19
If we take 8478 away from 8780, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 11:
3020 divided by 942 is 3 with a remainder of 194.
Write down 3 as next digit of the result. 
Result so far: 22878.193
If we subtract 2826 from 3020, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 12:
942 goes into 1940 2 times with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 22878.1932
The remainder is 56 after subtracting 1884 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
If we divide 560 by 942, we get 0 and a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 22878.1932
The remainder is 560 after subtracting 0 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 14:
The number 942 fits into 5600 5 times, leaving a remainder of 890.
Write down 5 as next digit of the result. 
Result so far: 22878.193205
Deduct 4710 from 5600 and we're left with 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

On to step 15:
942 can be fit into 8900 9 times, resulting in a remainder of 422.
The number 9 becomes the next digit in our result. 
Result so far: 22878.1932059
The remainder is 422 after subtracting 8478 from 8900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Let's proceed to step 16:
When dividing 4220 by 942, we get 4 with a remainder of 452.
Write down 4 as next digit of the result. 
Result so far: 22878.19320594
If we take 3768 away from 4220, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The final result is 22878.19320594 with a remainder of 4.52e-07.
